TiO2 nanorods arrays (TiO2 NRAs):Eu3+, Tb3+ decorated with Cs2CO3/CdS grown on carbon textiles coated with a TiO2-graphene (TiO2-G) thin film (TiO2-G/TiO2 NRAs:Eu3+, Tb3+/Cs2CO3/CdS) was fabricated. The as-prepared sample exhibits an excellent photodegradation performance under xenon (Xe) lamp light irradiation. The result indicates that the presence of Eu3+, Tb3+ can be excited by ultraviolet light to produce a high intensity visibe light absorbed by CdS, which can generate more photogenerated electron hole pairs. In addition, the presence of graphene is an important factor in accelerating the transferring of photogenerated electron to carbon textiles for photocatalytic reaction. This work can offer an alternative route for designing a hybrid structure system to utilize effectively broad-spectrum solar light and suppress the recombination of photogenerated electron-hole pairs.
