Abstract:
Photoelectrochemical water splitting is regarded as a promising strategy for the direct conversion of solar energy into hydrogen energy. However, detrimental bulk charge transport and surface trap-state-mediated carrier recombination result in low efficiency. Herein, we propose a dual hole transport layer strategy by combining a covalent organic polymer (CHN) framework and an inorganic NiOx layer to enhance the PEC performance of BiVO4 photoanode. The dual hole transport layers not only reinforce the built-in electric field but also reduce the surface-state-mediated charge recombination. The resulting BiVO4/CHN/NiOx/NiFeOx photoanode delivers a high photocurrent density of 4.45 mA/cm2 at 1.23 V versus RHE and excellent stability for continuous 24 h illumination. Overall, this work provides a versatile platform for interface engineering modulation of BiVO4 photoanodes, and sheds light on the mechanism of organic-inorganic hole transport layers for boosting PEC performance.

Spontaneous redox reactions occur abundantly in nature. The chemical reaction occurring in a disposable AA battery powering our remote controls is one such example of a spontaneous redox reaction. Another example is the immersion of coiled copper wire into an aqueous silver nitrate solution. The reaction shows a gradual, visually impressive color change from colorless to bright blue and the formation of a grey precipitate on the copper wire. In this experiment,...
