Abstract

Zinc molybdenum oxide (ZnMoO4) sub-micron plates were efficaciously synthesized by hydrothermal method for electro-catalytic energy conversion applications. Electron microscopic studies show plate like morphology of the synthesized materials. The electrochemical experiments were conducted to investigate the catalytic performance of ZnMoO4 for hydrogen evolution reactions (HER) in acidic medium using 0.5 M H2SO4 electrolyte. The onset over potential, over-potential at 10 mA/cm2, and Tafel of ZnMoO4 sub-micron plates for HER were found to be of ~45 mV, ~140 mV, and ~230 mV/dec respectively.
