AI Technical Summary
TiO2 photocatalytic materials suffer from narrow light absorption characteristics under visible light and severe recombination of photogenerated carriers, resulting in low photocatalytic efficiency and making them difficult to apply effectively in the field of metal corrosion protection.
BiOF nanoparticles were loaded onto a TiO2 nanotube array via a hydrothermal method to form a BiOF/TiO2 composite photoanode material. The narrow bandgap characteristics of BiOF were utilized to enhance the visible light response and suppress photogenerated carrier recombination.
It significantly improves the photocatalytic efficiency of TiO2 under visible light, prolongs the lifetime of photogenerated electrons, enhances the corrosion resistance of metals, and is suitable for humid and highly corrosive environments.
