Electrodeposition of Cobalt-Phosphate Oxygen Evolution Catalyst on Inert Electrode for Electrolysis

This study describes the electrodepositon of potentially competent oxygen evolution catalyst on inert anode using phosphate buffered solution containing cobalt ions. The thickness of deposited amorphous cobalt-phosphate catalyst thin film varies depending on the deposition potential and deposition time. The electrodeposited catalyst can actively be used to improve water oxidation reaction under neutral condition.
