Enhanced photocatalytic oxidation of arsenite to arsenate in water solutions by a new catalyst based on MoOx supported on TiO2

- Photocatalytic oxidation of As(III) to As(V) in aqueous samples.
- Catalysts based on molybdenum oxide supported on titania (MoOx/TiO2).
- Complete oxidation of As(III) on MoOx/TiO2.
- As(V) completely released into solution, avoiding catalyst deactivation.
- Photocatalytic reaction mechanism.
