摘要：This work reports on a novel BiOI/WO3 composite photoanode,which was fabricated by depositing BiOI onto a WO3nanoflake electrode through a electrodeposition method.The photoelectrochemical (PEC)activity of the BiOI/WO3 electrode for water splitting under visible-light irradiation was evaluated. The results show that the BiOI/WO3photoanode achieved a photocurrent density of 1.21mA-cm^-2 at 1.23V vs. reversible hydrogen electrode (RHE),which was higher than that of the bare WO3 nanoflake electrode (0.67mA·cm^-2).The enhanced PEC acticity of BiOI/WO3for water splitting can be attributed to the expansion of light absorption range as well as the facilitated separation of photo-generated carriers.
