“…As such, we think it is the ripe and right time to present a comprehensive, systematic, and up-to-date review on graphene-based photocatalysis from a whole scenario of viewpoint, considering the fast growth of literature reports in this field and that the development of this field is likely confronted with a bottleneck period. Although there have been some reviews and book chapters on this topic, − they only focus on summarizing the preparation methods and/or some selected photocatalytic reactions of graphene-based composites. None of the previous reviews and book chapters − have covered all the reported photoredox types over the graphene-based composite photocatalysts, the elaborate understanding of the fundamental roles of graphene in promoting the photocatalytic performance and, particularly, charge carrier dynamics in the graphene-based composites, the comparison between graphene-based and other carbon allotropes-based composite photocatalysts, the existing problems and challenges in this field, and how and what we should rationally consider for applying the graphene-based composite photocatalysts to practical applications in solar energy conversion.…”
