Profile Summary

PhD in Chemistry (RGIPT, 2021–2024) specializing in transition metal-based catalysts for green hydrogen production via efficient anodic half-reactions, including sulfion oxidation from industrial/wastewater, biomass-derived glycerol/methanol oxidation, and water oxidation. Expert in advanced characterization techniques such as XRD, FESEM, TEM, Raman, EXAFS, NMR, and XPS to elucidate nanomaterial structures and performance. Proven track record in material chemistry, electrochemistry, H2S splitting, waste utilization, and sustainable energy solutions. Committed to professional excellence, honesty, and hard work, I seek freelance opportunities to drive innovation in advanced materials—developing catalysts, analyzing electrochemical data, optimizing green H2 processes, or consulting on waste-to-energy projects. Let's collaborate to advance your research or startup goals with cutting-edge expertise.
