Porous BiVO₄/Boron-Doped Diamond Heterojunction Photoanode with Enhanced Photoelectrochemical Activity.

ABSTRACT: Constructing heterojunction is an attractive strategy for promoting photoelectrochemical (PEC) performance in water splitting and organic pollutant degradation. Herein, a novel porous BiVO₄/Boron-doped Diamond (BiVO₄/BDD) heterojunction photoanode containing masses of ultra-micro electrodes was successfully fabricated with an n-type BiVO₄ film coated on a p-type BDD substrate by magnetron sputtering (MS). The surface structures of BiVO₄ could be adjusted by changing the duration of deposition (T_d). The morphologies, phase structures, electronic structures, and chemical compositions of the photoanodes were systematically characterized and analyzed. The best PEC activity with the highest current density of 1.8 mA/cm² at 1.23 V
