Spinel oxides are widely used to enhance photoanodes' photoelectrochemical (PEC) water oxidation performance. In this paper, we demonstrate that a p-type photothermal MnCo2O4 layer, inserted between BiVO4 and FeOOH cocatalysts, can significantly PEC On the one hand, charge recombination is greatly suppressed since form p-n heterojunction with n-type BiVO4. other upon near-infrared (NIR) light irradiation, deposited shows excellent conversion performance further facilitate transfer accelerate process by elevating operating temperature. addition, cocatalyst introduced fully utilize holes reaching surface oxygen evolution kinetics. Consequently, carefully constructed BiVO4/MnCo2O4/FeOOH photoanode photocurrent (4.71 mA cm-2) at 1.23 V vs RHE (VRHE) superior applied bias photon-to-current efficiency (1.62%) 0.6 VRHE. The density maintains more than 90% of initial after 4 h combined solar NIR irradiation. Enhancing catalytic activity photoelectrodes using materials simple effective strategy, which be explore enhancement in photoelectrodes.
