The Self-Passivation Mechanism in Degradation of BiVO4 Photoanode [PDF]
iScience, 2019 BiVO4 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 Na2SO4 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 (Bi2O3, Bi4O7).

Photocorrosion Mechanism of TiO2-Coated Photoanodes [PDF]
International Journal of Photoenergy, 2015 Atomic layer deposition was used to coat CdS photoanodes with 7 nm thick TiO2films to protect them from photocorrosion during photoelectrochemical water splitting. Photoelectrochemical measurements indicate that the TiO2coating does not provide full protection against photocorrosion.

Controlled Porosity in Ferroelectric BaTiO3 Photoanodes
ACS Applied Materials & Interfaces, 2022 The use of ferroelectric polarization to promote electron-hole separation has emerged as a promising strategy to improve photocatalytic activity. Although ferroelectric thin films with planar geometry have been largely studied, nanostructured and porous ferroelectric thin films have not been commonly used in photo-electrocatalysis.
