Photoelectrochemical deposition of CoP on cuprous oxide photocathodes for solar hydrogen production

Photoelectrochemical (PEC) water splitting is an attractive and sustainable energy conversion method. In this work, cobalt phosphide (CoP) is photoelectrochemically deposited on a p-type cuprous oxide (pCu(2)O) photocathode for solar hydrogen production. Under visible light irradiation, the PEC assembly is active for hydrogen evolution, generating a current density of up to -5.3 mA cm(-2) and -4.2 mA cm(-2) in acidic and basic conditions at 0 V vs. the reversible hydrogen electrode (RHE).
