Microwave-assisted synthesis of an RGO/CdS/TiO step-scheme with exposed TiO {001} facets and enhanced visible photocatalytic activity.

Semiconductor-based heterojunction photocatalysts with a special active crystal surface act as an essential part in environmental remediation and renewable energy technologies. In this study, an RGO/CdS/TiO step-scheme with high energy {001} TiO facets was successfully fabricated a microwave-assisted solvothermal method. The photocatalytic performance of as-prepared samples was assessed by degrading methylene blue under visible light irradiation.
