BiVO<sub>4</sub> is a promising photoanode material for solar-assisted water splitting in a photoelectrochemical cell but has a propensity to degrade. Investigations carried out here in 0.1 M Na<sub>2</sub>SO<sub>4</sub> electrolyte showed that degradation is by dissolution of V in the electrolyte while Bi is retained on the anode probably in the form of solid Bi oxide (Bi<sub>2</sub>O<sub>3</sub>, Bi<sub>4</sub>O<sub>7</sub>). Accumulation of Bi oxide on the anode surface leads to passivation f ...[more]
