Preparation of reduced graphene oxide/meso-TiO2/AuNPs ternary composites and their visible-light-induced photocatalytic degradation n of methylene blue

Reduced graphene oxide/meso-TiO2/AuNPs (RGO/meso-TiO2/AuNPs) ternary composites were prepared via the addition of graphene oxide to the dispersion of meso-TiO2/AuNPs under a hydrothermal condition. The RGO/meso-TiO2/AuNPs ternary composites show high photocatalytic activity toward MB.
