Hybrid Photoelectrocatalytic TiO₂-Co₃O₄/Co(OH)₂ Materials Prepared from Bio-Based Surfactants for Water Splitting.

ABSTRACT: The development of new photoanode materials for hydrogen production and water treatment is in full progress. In this context, hybrid TiO₂-Co₃O₄/Co(OH)₂ photoanodes prepared using the sol-gel method using biosurfactants are currently being developed by our group. The combination of TiO₂ with a cobalt-based compound significantly enhances the visible absorption and electrochemical performance of thin films, which is mainly due to an increase in the specific surface area and a decrease in the charge transfer resistance on the surface of the thin films. The formation of these composites allows for a 30-fold increase in the current density when compared to cobalt-free materials, with the best TiO₂-CoN0.5 sample achieving a curren
