| Abstract | Delafossite CuFeO2 is a promising photocathode material for cost-efficiently photoelectrochemical (PEC) water splitting, but the unfavorable conductivity and fast recombination dynamics of photogenerated carriers limit its PEC activity for water reduction. Here, we developed a heterostructure photocathode consisting of the Cu-doped NiO (Cu:NiO) hole selective layer (HSL) and Ni-doped CuFeO2 (Ni:CuFeO2) active layer by simply annealing a homogeneous Cu-Fe oxalate layer grown on the Ni film deposited on the fluorine doped tin oxide (FTO) substrate. The obtained heterostructure of Cu:NiO/Ni:CuFeO2 with enhanced charge carrier transportability and high-quality interface greatly promotes the separation of photogenerated carriers. Accordingly, the Cu:NiO/Ni:CuFeO2 photocathode exhibits a high photocurrent density of similar to 0.9 mA.cm(-2) at 0.2 V (vs. reversible hydrogen electrode, RHE), outperforming most of the reported bare CuFeO2 photocathodes in the literature. And the photocurrent density can be further improved to 1.2 mA.cm(-2) after decorating NiSx cocatalyst. |
