Abstract

BiVO₄ mesoporous single crystals (MSCs) were successfully prepared, for the first time, by a one-step hydrothermal method using the acidified BiVO₄ precursor solution pre-impregnated silica as the template. It was revealed that the BiVO₄ MSCs were formed by a double-diffusion mechanism. The O₂ evolution rate over BiVO₄ MSCs was improved nearly 10 times than that over BiVO₄ bulk single crystals.
