Abstract
In this paper we developed a template-assisted three-dimensionally ordered BiVO4 inverse opal (IO) film by sandwich-type infiltration through self-assembled colloidal polystyrene (PS) opal beads with a diameter of 410 nm (±20 nm) for photoelectrochemical hydrogen production. Herein, the ordered BiVO4 inverse opal structure possessed a pore diameter of ∼340 nm and wall thickness of ∼20 nm, providing a large surface area. Their photoelectrochemical behavior were assessed under 1 sun illumination (100 mW/cm2 with AM 1.5 filter) in 0.5 M Na2SO4 (pH 7) which displayed a photocurrent density (Jsc) of 0.8 mA/cm2 at 1.23 V vs a normal hydrogen electrode (NHE). Low photocurrents of BiVO4 IO photoelectrodes are due to their limited photoelectrochemical ability to split water under light irradiation and their intrinsically low electronic conductivities. To overcome these problems, BiVO4 IO film was modified to deposit a nanolayer of n-type FeVO4 having a narrow band gap (Eg = 2.06 eV). The bilayered BiVO4/FeVO4 core...
