    Abstract Manganese oxides (MnO 2 ) with nanowire morphology materials are promising candidates for improving oxygen evolution and oxygen reduction reaction (OER/ORR) performance. In this work, we developed transition metal cation doping strategy into the α‐MnO 2 tunnel structure to tune the Mn oxidation states and control the uniform nanowire morphology, crystalline structure to investigate the effect of doping over bifunctional activity. The single Ni 2+ cation doping in α‐MnO 2 with various loading concentrations resulted in 8Ni−MnO 2 exhibiting remarkable OER and ORR activity owing to their excessive concentration of Mn 3+ and Mn 4+ octahedral sites respectively. Further, Co 2+ cation doping in 8Ni−MnO 2 leads to an enhanced synergistic effect that significantly improves the fraction of Mn 3+ quantity which is confirmed by average oxidation state. For electrochemical OER performance, 8Co−8Ni−MnO 2 exhibits a potential of 1.77 V, Tafel slope value of 68 mV dec −1 and lower charge transfer resistance and it is active in ORR with more positive onset potential of 0.90 V, half‐wave potential of 0.80 V, better current density (4.7 mA cm −2 ) and a four‐electron pathway. Moreover, bifunctional activity (ΔE=E OER @10 mA cm −2 – ORR@E 1/2 ) of 8Co−8Ni−MnO 2 demonstrated 0.97 V, indicates an excellent activity in alkaline electrolyte solution.

    The valorization of CO2 via renewable energy sources allows one to obtain carbon-neutral fuels through its hydrogenation, like methane. In this study, Ni0.05Ce0.95O2−δ catalysts were prepared using a simple one-pot hydrothermal method yielding nanorod and nanocube particles to be used for the methanation reaction. Samples were characterized by XRD, BET, TEM, H2-TPR, and H2-TPD experiments. The catalytic activity tests revealed that the best performing catalyst was Ni0.05Ce0.95O2−δ, with nanorod morphology, which gave a CO2 conversion of 40% with a selectivity of CH4 as high as 93%, operating at 325 °C and a GHSV of 240,000 cm3 h−1 g−1. However, the lower activation energy was found for Ni0.05Ce0.95O2−δ catalysts with nanocube morphology. Furthermore, an in operando diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) analysis was performed flowing CO2:H2 or CO:H2 mixture, showing that the main reaction pathway, for the CO2 methanation, is the direct hydrogenation of formate intermediate.

    Abstract Design and development of an efficient and earth abundant electrocatalyst for improving the kinetics of oxygen reduction reaction (ORR) is considered as important task especially in renewable energy sector and energy‐intensive appliances. In particular, developing a low cost, environmental benign, robust and stable ORR catalyst still remains a challenging task due to its sluggish kinetics. Here in this work we developed a simple and environmentally green electro‐spinning technique for decoration of cobalt oxides (Co 3 O 4 ) on polyacrylonitrile (PAN) fibers to generate a hybrid nanostructure of carbon nanofiber‐ Co 3 O 4 (CNF‐ Co 3 O 4 ) during calcinations and employed resultant electrocatalyst towards ORR. The CNF provided active surface to seed as well an anchoring spot for nanocrystals and act as a conducting network. The resulting CNF‐Co 3 O 4 hybrid displayed a supeior ORR current density that surpassed bare CNF and occurred via a 4 electron direct reduction pathway. It may due to the as formed heterogeneous interface during the decoration of Co 3 O 4 on CNF leads to enhanced conductivity and thereby decreases ORR overpotential as well as enhanced reaction rate at CNF‐Co 3 O 4 surface.
  • Investigation on Template Etching Process of SBA-15 Derived Ordered Mesoporous Carbon on Electrocatalytic Oxygen Reduction Reaction

    Chemistryselect, 2019
    Abstract Ordered mesoporous carbon (OMC) is a promising material for oxygen reduction reaction (ORR) in fuel cells owing to its high surface area and more number of catalytic active sites. Herein, OMC was synthesized by hard template method, i. e., nanocasting of sacrificial silica template (SBA‐15) and then the sacrificial template was abolished using three different etching chemicals namely, hydrofluoric acid (HF), sodium hydroxide (NaOH) and polyvinylidene fluoride (PVDF) respectively, in order to study the etching effect. The etched OMCs derived from the SBA‐15 template was confirmed by various characterization techniques. In OMC, the porous nature, surface morphology and defect density changes with respect to etching chemicals were evidently determined. From the electrochemical studies, it has been concluded that the NaOH etched OMC showed higher electrocatalytic activity than others by exhibiting more positive onset (0.83 V), half‐wave potential (0.75 V), high current density (3.3 mA/cm 2 ), Tafel slope (83 mV/dec) and n‐value (2.4). Eventually, the electrochemical impedance study (EIS) was performed to determine the charge transfer resistance (R ct ) of various etched OMCs and has been found that NaOH etched OMC shows the lowest R ct value due to the presence of more defective sites and result in enhancing oxygen adsorption during ORR.
  • 2D and 3D Silica-Template-Derived MnO2 Electrocatalysts towards Enhanced Oxygen Evolution and Oxygen Reduction Activity

    Chemelectrochem, 2018
    Abstract In this work, a hard‐template‐based nano‐replication process is employed to prepare mesoporous MnO 2 materials. We adopted four silica materials, namely, SBA‐15, KIT‐6, MCM‐41, and MCM‐48 as templates to prepare MnO 2 materials by using a nanocasting route. The structural characteristics of the resultant MnO 2 materials were thoroughly investigated by using XRD, BET, FESEM, HR‐TEM, XPS, and Raman techniques. All studies confirmed the replication of porous MnO 2 nanostructures from silica supports in β‐crystallographic form. By employing X‐ray absorption near‐edge structure (XANES) and extended X‐ray absorption fine structure (EXAFS), we identified the existence of Mn and oxygen vacancies in the developed MnO 2 material. The hydrodynamic linear sweep voltammetric technique was employed to demonstrate the efficient oxygen evolution reaction (OER) and oxygen reduction reaction (ORR) activity of the catalyst in 0.1 M KOH solution. The KIT‐6‐derived MnO 2 nanostructure displayed equal activity to the benchmark catalyst RuO 2 . This work lays a foundation to prepare and employ ordered mesoporous MnO 2 materials as OER/ORR catalysts, which have potential applications in electrochemical energy conversion and storage devices.

    Tris(4-isocyanatophenyl)methane (TIPM) and N,N′-dimethylformamide react at room temperature with no externally added catalyst to yield polyisocyanurate (PIR) gels. The obtained PIR gels were converted to N- and S-doped porous carbon monoliths by thermal treatment at 1000 °C with elemental sulfur under inert conditions. The PIR linkage acts as precursor for carbon and nitrogen, and %S doping was varied by changing the concentrations of elemental sulfur during pyrolysis. The optimized concentration of sulfur (5.6%) into the carbon matrix displayed excellent oxygen reduction activity with direct four-electron transfer relative to its pristine counterparts by (1) introducing micro- and mesopores in addition to the already existing macropores by etching the carbon surface (confirmed by N2 sorption isotherms and microscopic images) with the increase in the external surface area providing more active centers and efficient diffusion of electrolyte ions, (2) providing more – C–S–C– active species than oxidized sul...
