Abstract

One-step synthesis of CdS-TiO ₂-chemically reduced graphene oxide (RGO) composites was carried out using microwave-assisted reduction of graphite oxide in CdS precursor solution with TiO ₂ suspension. The photocatalytic performance of CdS-TiO ₂-RGO composites in degradation of methyl orange was examined. Results show that the RGO addition could enhance the photocatalytic performance of CdS-TiO ₂ composites with maximum degradation efficiency of 99.5% under visible light irradiation as compared with the pure TiO ₂ (43%) and CdS-TiO ₂ (79.9%) composites due to the increase of specific surface area for more adsorbed MO and the reduction of electron-hole pair recombination with the introduction of RGO.
