Influence of pH on the properties of tungsten trioxide synthesized by the hydrothermal method Daniel C. Costa, Caique D.A. Lima, Marcelo E.H.M. Costa, Cleânio L. Lima, Italo Alefi Lima dos Santos, Gardênia de Sousa Pinheiro, Rodrigo Prioli Menezes, Carlos Alberto Senna, Suellen D.T. Barros, Guilherme C. Concas, Bruno G. Silva, Rubem L. Sommer, Jefferson F.D.F. Araújo Solid State Sciences, 2026 Tungsten trioxide (WO 3 ) is a semiconductor oxide that has attracted scientific interest due to its structural versatility and functional properties, making it a promising material for various applications, such as photocatalysis. However, these properties strongly depend on the synthesis conditions, which determine the crystalline phase, morphology, and the presence of structural defects, such as oxygen vacancies. In this context, this work aims to investigate the influence of pH on the structural and physical properties of WO 3 . The results reveal that pH is a critical parameter in the formation of different crystalline phases of WO 3 , including hexagonal and orthorhombic structures, as confirmed by X-ray diffraction and electron microscopy analyses. Raman spectroscopy and Fourier Transform Infrared Spectroscopy corroborate these findings by highlighting characteristic vibrational modes and band shifts, indicating pH-induced structural changes. Magnetic measurements reveal a systematic evolution from purely diamagnetic behavior at low pH to a weak ferromagnetic-like response at higher pH values, characterized by a small hysteresis loop superimposed on a dominant diamagnetic background. These results highlight pH as a key parameter for tailoring the phase composition, defect landscape, and defect-induced magnetic response of WO 3 structures.
In situ investigation of structural stability and reversible conformational changes in Gd2(WO4)3 at high temperatures Jailson dos Santos Silva, Antonio Werbeson Miranda, Italo Alefi Lima dos Santos, Ediomar Costa Serra, João Victor Barbosa Moura, Alan Silva de Menezes, Paulo de Tarso Cavalcante Freire, Gardênia de Sousa Pinheiro, Cleânio da Luz Lima Journal of Molecular Structure, 2026 • In situ PXRD reveals anisotropic thermal expansion along the b and c axes • In situ Raman detects reversible local conformational changes near 523 K • Combined PXRD-Raman analysis links long-range stability to local vibrational dynamics In this work, Gd 2 (WO 4 ) 3 samples were synthesized by the hydrothermal method and subsequently calcined at 923 K, being characterized at room temperature by X-ray diffraction, UV-Vis spectrophotometry and Raman spectroscopy, in addition to in situ PXRD and Raman measurements under variable temperature conditions. Rietveld refinement confirmed the exclusive formation of the monoclinic phase (space group C2/c ). The in situ PXRD analyses, performed between 298 K and 773 K, revealed high long-range structural stability, evidenced by anisotropic thermal expansion that is more pronounced along the b (11.9(4) × 10 -6 K -1 ) and c (10.3(4) × 10 -6 K -1 ) axes than the a (2.2(6) × 10 -6 K -1 ) axis. The b/c ratio exhibited a non-linear trend: a continuous increase followed by an abrupt decrease around 523 K during both heating and cooling cycles, suggesting a subtle conformational modification within the crystal lattice. Consistently, in situ Raman spectroscopy indicated reversible local changes in the same temperature range (538 K), variation in intensity, as well as, shifts of vibrational modes associated with WO 4 2- tetrahedra. These effects were attributed to enhanced phonon-phonon anharmonicity and rearrangements of GdO 8 polyhedra. The results demonstrate that although the global structure of Gd 2 (WO 4 ) 3 remains monoclinic throughout the investigated temperature range, reversible local reorganizations occur, revealing an intrinsic thermal sensitivity of the lattice and supporting its potential use in thermally stable photonic and optoelectronic applications, such as Raman-based temperature sensors, high-temperature optical components, and rare-earth-doped laser host materials.
Temperature–dependent phase behavior and thermal stability of bismuth-doped tungsten trioxide nanowires Antonio Werbeson Miranda, Caique Diego de Abreu Lima, João Victor Barbosa Moura, Alan Silva de Menezes, Clenilton Costa dos Santos, Emerson da Silva do Nascimento, Moisés das Virgens Santana, José Ferreira da Silva Júnior, Paulo de Tarso Cavalcante Freire, Gardênia de Sousa Pinheiro, Cleânio da Luz Lima Solid State Communications, 2025
Surface Sensitivity of Mesoporous Carbon-Supported Iron Catalysts in the Fischer–Tropsch Synthesis: An In Situ XPS Site Evolution at Distinct Reaction Conditions João Pedro S. Nascimento, Alcineia C. Oliveira, Fabiano A.N. Fernandes, Gardênia S Pinheiro, Juan Pedro Holgado, Alfonso Caballero Martinez, Olga Guerrero-Pérez, José Jiménez-Jiménez, E. Rodríguez-Castellón Energy and Fuels, 2025 The Fischer–Tropsch process can be considered as an alternative route to convert fossil fuels such as crude oil, coal, and methane for the production of more environmentally friendly liquid fuels and chemicals. As recoverable sources of carbon, Fischer–Tropsch synthesis (FTS) converts a mixture of CO and H2 to a range of hydrocarbons, which is free of sulfur and nitrogen and low in aromatics. The surface-sensitive investigation of the temperature and pressure effects on the FT synthesis performance over mesoporous carbon-supported iron catalysts was examined by in situ X-ray photoelectron spectroscopy analyses. Raman and Mössbauer spectroscopy measurements illustrated the structural properties of mesoporous Fe-based oxides. Under FTS reaction conditions of 20 and 30 atm, and temperatures of 240, 255, and 270 °C with a CO-to- H2 ratio of 1, the solids were active with 38–45% of CO conversion and a rate of 1 × 10–5 molCO·g–1·s–1. The product distribution gave C1–C4, C5–C9, and C10+ products with the structure of the solid marginally affected by the type of product obtained. The in situ surface XPS analyses were conducted at ∼240–270 °C and 10 atm with a CO-to-H2 ratio of 1 for 1 h. The α-Fe2O3 phase was reduced to Fe3O4 resulting in well-dispersed magnetite nanoparticles with further reduction to metallic iron on the mesoporous carbon support. Such α-Fe phase demonstrated accessibility of the syngas resulting in the activity of the solids. The chemical evolution of the Fe 2p, O 1s, C 1s, and K 2s core levels during the FTS with increasing the temperature up to 255 °C suggested that the surface carburization formed χ-Fe5C2 and θ-Fe3C iron carbide phases along with Fe3O4 and, tentatively, the metallic iron phase. The mesoporous carbon-supported iron catalysts having χ-Fe5C2 carbide determined the activity and stability during the FTS synthesis.
Preparation and Application of Sodium-Lanthanum Molybdate for the Photocatalytic Degradation of Coomassie Brilliant Blue G-250 Dye Caique D. A. Lima, Joyce A. Borges, Italo A. L. Santos, Angel A. Hidalgo, Josy A. Osajima, Adriel da Silva Almeida, Thiago M. B. F. Oliveira, Jefferson F. D. F. Araujo, Suellen D. T. de Barros, Marcelo E. H. Maia da Costa, Diego A. B. Barbosa, João V. B. Moura, Gardênia S. Pinheiro, Cleânio L. Lima ACS Omega, 2025 High Resolution Image Download MS PowerPoint Slide This study reports on the synthesis, characterization, and application of sodium–lanthanum molybdate [NaLa(MoO 4 ) 2 ] as a photocatalyst in the degradation process of Coomassie Brilliant Blue G-250 (CBB-250), an environmentally toxic and recalcitrant dye derived from triphenylmethane. The highlighted ceramic material was produced by coprecipitation, and its properties were studied using a range of physicochemical techniques including compositional, crystallographic, and morphological analyses. Among the most relevant information, X-ray diffraction (XRD), Raman spectroscopy, and Fourier transform infrared (FTIR) spectroscopy confirmed the formation of NaLa (MoO 4 ) 2 crystals with a tetragonal arrangement. Additionally, the scanning electron microscope (SEM) images provide evidence of the production of overlapping plate-like microstructures. The nitrogen adsorption isotherms demonstrated that the molybdate obtained exhibits mesoporous organization, with a surface area and pore diameter equivalent to 45.7 m 2 g –1 and 6.54 nm, respectively. Photocatalytic tests, performed under ultraviolet light irradiation for 120 min, indicated that NaLa(MoO 4 ) 2 has high oxidative reactivity, achieving a degradation of >95% of the CBB-250 dye present in the system. The reaction velocity constants, estimated in accordance with the Langmuir–Hinshelwood equation, substantiate that NaLa(MoO 4 ) 2 enhances the reaction kinetics (13.7 × 10 –3 min –1 ) throughout the photochemical treatment. In light of the growing scientific interest in effective strategies for the removal of emerging pollutants from contamination matrices, NaLa(MoO 4 ) 2 represents a promising avenue for the development of innovative technologies in this field.
Magnetic transition in MoO3: Influence of Mo5+/Mo6+ ratios on paramagnetic to diamagnetic behavior Caique D.A. Lima, Thais C.V. de Carvalho, Cesar D. Mendoza, Marcelo E.H. Maia da Costa, Gardênia de S. Pinheiro, Cleânio Luz-Lima, Bruno G. Silva, Rubem L. Sommer, Jefferson F.D. F. Araujo Solid State Sciences, 2025 This study examines the transition from paramagnetic to diamagnetic response in MoO 3 , a phenomenon previously documented in the literature where the magnetic response of MoO 3 varies with the applied field, changing from paramagnetic at low fields to diamagnetic at high fields. MoO 3 samples were synthesized with controlled Mo 6+ /Mo 5+ ratios while maintaining high crystallinity to elucidate this phenomenon. The samples were prepared in a chemical vapor deposition (CVD) furnace under an oxygen environment at two different temperatures, 550 and 650 °C, and two annealing times, 4 and 8 h. The resulting samples were subjected to characterization using powder X-ray diffraction (XRD), Raman spectroscopy, Fourier transform infrared (FTIR) spectroscopy, X-ray photoelectron spectroscopy (XPS), and vibrating sample magnetometry (VSM). The XRD results demonstrated the formation of highly crystalline MoO 3 in all samples, which is confirmed by Raman and FTIR. The XPS results demonstrate the concentration of Mo 5+ and Mo 6+ present in each sample. The results of the VSM experiments demonstrated that the observed change in the magnetic response of MoO 3 is due to the intensity of the material's response being comparable to that of the sample holder's response. Moreover, vibrating sample magnetometry and X-ray photoelectron spectroscopy analysis revealed that MoO 3 can exhibit both paramagnetic and diamagnetic behavior, depending on the quantity of Mo 5+ present in the sample. • The study explores the paramagnetic-to-diamagnetic transition in MoO3 influenced by applied magnetic fields and Mo6+/Mo5+ ratios. • MoO3 samples with controlled Mo6+/Mo5+ ratios were synthesized via thermal decomposition of ammonium heptamolybdate under varying conditions. • Characterization confirmed high crystallinity and quantified Mo5+/Mo6+ concentrations. • Magnetic behavior transitions were linked to Mo5+ content of the sample.
Investigation of Mn2+-Doped Stearic-Acid Through XRD, Raman, and FT-IR, and Thermal Studies Rodrigo M. Rocha, Marinaldo V. de Souza Junior, Luiz F. L. Silva, Paulo T. C. Freire, Gardênia S. Pinheiro, Waldomiro Paschoal, Francisco F. de Sousa, Sanclayton G. C. Moreira Quantum Beam Science, 2025 In this research, we investigated the influence of Mn2+ ions on the packing in stearic acid (SA) crystals through the use of Raman spectroscopy, X-ray diffraction (XRD), and Fourier transform infrared (FT-IR) spectroscopy. The crystals investigated were obtained utilizing the slow evaporation methodology in a hexane solution under varying manganese (Mn) concentrations sourced from MnSO4 5H2O (0.5, 1.0, 1.5, 2.0, 4.0, and 6.0%). XRD studies indicated that all SA crystals were grown in the Bm form (monoclinic), favoring the gauche conformation in molecular packing. Additionally, crystalline lattice modifications were observed through Raman spectral changes in the low-vibrational energy region. Variations in the intensities and Raman shifts in two lattice vibrational modes, centered at approximately 59 and 70 cm−1, revealed that two types of hydrogen bonds are distinctly affected within the crystalline lattice. Furthermore, the unit cell parameters (a, b, c, and β) were determined via Rietveld refinement, and their behavior was analyzed as a function of Mn concentration. The results indicated that Mn2+ ions exert a strain and deformation effect on the unit cell. Lastly, differential scanning calorimetry (DSC) was employed to evaluate the thermal stability of the Bm form of SA crystals.
