Research progress on graphene-based nano-photocatalysts
Abstract:Recently, the development of graphene has aroused extensive attention due to its exceptional properties. The flat two-dimensional carbon layer can anchor nanomaterials, such as nanophotocatalysts, and improve their performances. In this paper, the recent advances in the preparation methods of graphene have been reviewed. Subsequently, the preparation and properties of graphene-based photocatalysts are introduced, in which the research progress of graphene-TiO2 and their performances are highlighted. The review ends with some perspectives on the challenges and opportunities in the future development of grapheme-based photocatalysts.?????
