Water splitting for hydrogen production

Abstract

Water splitting through alkaline electrolysis offers a promising route for sustainable hydrogen production amid growing environmental and energy challenges. This project addresses the need for stable, efficient, and economically feasible electrocatalysts for the oxygen evolution reaction in alkaline environments, where non-precious cobalt based materials have emerged as attractive candidates. The study focuses on the synthesis of cobalt oxyhydroxide via the oxidation of cobalt hydroxide and its thorough characterization using X-ray diffraction and scanning electron microscopy. The work also explores how catalyst loading and pH conditions influence the integration of these electrocatalysts within membrane electrode assemblies, with the overall aim of informing catalyst design strategies that enhance water splitting efficiency and contribute to scalable green hydrogen production.
