Deciphering methanolysis of modified waste coconut scum oil into biodiesel using green NaOH/SnO2 nanocatalyst: Optimization, thermo-kinetics, cost-evaluation and diesel engine studies K.V. Yatish, B.R. Omkaresh, E. Amruth, Mounesh, K.N. Prashanth Energy, 2025 High-quality biodiesel production mainly depends on the quality of the feedstock utilized. Improving the feedstock quality is greatly desired and can be applied to any feedstock to increase biodiesel production. Waste coconut scum oil (WCSO) is treated with cyclo-pentyl-methyl ether (CPME) to improve the miscibility and mass transfer for biodiesel generation. The sodium hydroxide integrated with tin oxide nanoparticles (NaOH/SnO 2 NPs) is used as an effective catalyst for treated-feedstock biodiesel production. Initially, SnO 2 NP S are synthesized using A. polystachya leaves extract and synthesized SnO 2 is characterized through various techniques. A maximum yield of 99.7 % is achieved under the conditions of 10 % v/v CPME co-solvent, a 3 wt%SnO 2 /0.15 wt%NaOH catalyst concentration, reaction temperature of 60 °C, molar ratio of 11:1, reaction time of 40 min, and an agitation speed of 600 rpm. Notably, NaOH/SnO 2 showed excellent reusability up to the 6th cycle, and the fuel properties treated with CPME showed good properties compared to bare feedstock. The calculated activation energy for conversion of oil to methyl esters was found to be 38.19 kJ/mol, and the frequency factor was 2.2 × 10 4 min −1 . The thermodynamic analysis shows that the enthalpy and entropy of the activation process are found to be 35.47 kJ/mol and −0.17 kJ/mol.K, respectively. The economic analysis demonstrated that, the cost of biodiesel using NaOH/SnO 2 nanocatalyst is 78.74 ($0.90). Further, addition of CPME in the biodiesel/diesel blend improved various performance parameters. At 3.48 kW, 1.33 % of BTE increases using B20-15CPME, whereas B20-5CPME decreases, at 0.87 kW, 3.4 % decreases and at 3.49 kW, BSFC increases using B20-15CPME. At 3.48 kW, carbon monoxide (CO) and hydrocarbon (HC) decrease to 48 % and 5.65 %, respectively, carbon dioxide (CO 2 ) and nitrogen oxides (NOx) increase to 9.37 % and 16.53 %, compared to diesel fuel.
Triphenylamine-Based Dual Chemosensor for Cu2+ and Co2+ Ions and Volatile Acid Vapour Sensor, DFT Calculations Aravind R. Nesaragi, Jyoti Nagalik, Mounesh, Sharanakumar T. M., Halligudra Guddappa, Tahani Mazyad Almutairi, Sanjeev R. Inamdar, Anup Pandith Applied Organometallic Chemistry, 2025 In this work, a novel fluorescent chemosensor 3‐(2‐(2‐(4‐(diphenylamino)phenyl)‐4,5‐diphenyl‐1H‐imidazol‐1‐yl)thiazol‐4‐yl)‐2H‐chromen‐2‐one (TCCM) was effectively synthesized and characterized through NMR and Mass spectrum. An approach towards the recognition of Cu2+ and Co2+ ions using a turn‐off fluorescence technique was developed. The chemosensor TCCM also exhibited colorimetric and fluorometric sensing behaviour with a visible colorimetric response to trifluoroacetic acid (TFA). Upon the addition of TFA to TCCM, a new peak formation at 500 nm in the absorption spectra along with the visible colour change from colourless to brown. In addition, it exhibits high selectivity towards Cu2+ and Co2+ ions with a limit of detection of 4.2 and 3.9 μM, respectively. It was discovered that the sensor was quite selective for Cu2+ and Co2+ ions that had a lot of competing ions. Further, the studies were supported by DFT analysis and NBO studies.
Non-Precious Tetra-(4-methylthiazole)-carboxamide Cobalt(II) Phthalocyanine Supported on Functionalized Carbon Nanotubes as an Efficient Electrocatalyst for a Hydrogen Evolution Reaction Mounesh, B. A. Thippeswamy, Pramod Shiralkar, R. Geetha Balakrishna, B. M. Nagaraja, K. Pramoda ACS Applied Energy Materials, 2025 Hydrogen production by water splitting has gained significant attention due to a rise in demand for sustainable hydrogen fuel. In the present study, we report the synthesis of a novel, low-cost tetra-(4-methylthiazole)-carboxamide cobalt(II) phthalocyanine coordination polymer compound, denoted CoTMTCAPc, utilizing it as a catalyst for an electrocatalytic hydrogen evolution reaction (HER). This CoTMTCAPc compound shows satisfactory HER activity with an overpotential of 172 mV (vs RHE) at 10 mA cm –2 and a Tafel slope of 147 mV dec –1 . To further improve its electrocatalytic HER performance, the CoTMTCAPc compound is coupled with carboxyl-functionalized multiwalled carbon nanotubes (f-MWCNT). The synthesized CoTMTCAPc/f-MWCNT nanocomposite demonstrates HER activity on par with the benchmark Pt/C catalyst with an overpotential of 81 mV (vs RHE) at 10 mA cm –2 and a Tafel slope of 41 mV dec –1 with excellent stability. A mixture of CoTMTCAPc and bare MWCNT (without functionalization), on the other hand, does not give any notable hydrogen evolution activity. The piled-up CoTMTCAPc and f-MWCNT moieties are held together by van der Waals attraction and exhibit robust HER activity under harsh chemical conditions. Second, surface functionalities of f-MWCNT enhance dispersibility and assist in a homogeneous distribution of individual components, thereby improving charge-transfer interactions. The extraordinary HER performance of the CoTMTCAPc/f-MWCNT nanocomposite is attributed to abundant active sites due to homogeneously distributed CoTMTCAPc over f-MWCNT and improved electronic conductivity and charge-transfer rate. The coupling of the CoTMTCAPc moiety with f-MWCNT appears to be advantageous for electrocatalysis and other related applications.

Manikanta, Komal N. Patil, Mounesh, Itika Kainthla, Siddappa A. Patil, Bhari Mallanna Nagaraja Catalysis Reviews Science and Engineering, 2025 In the present review, we aim to provide important insights into copper-based heterogeneous catalytic systems and discuss the conversion of furfural (FF) through hydrogenation. Each discussed catalyst and the support used for the catalytic reactions play a vital role in the reaction mechanism along with different factors enhancing the catalytic activity. Also, the importance of Cu-based materials along with support, the importance of solvent in the liquid-phase reaction, and the importance of pre-reduction of catalysts are explained in detail. In addition, the superior activity of the catalyst and a few reports from the last decade for Cu-based catalytic systems have been summarized along with the tabulation of different synthesis procedures, mechanistic study, and detailed descriptions with tables and figures. Finally, the conclusions with future aspects for the development of the catalytic hydrogenation process via Cu-based catalytic systems are overviewed.
