Photocatalitic Application of Graphene

Graphene, an allotrope of carbon, is a single carbon atomic layer of graphite that has specific electrical and optical properties, high conductivity and a large specific surface area. Thus, it has been regarded as an important component for making various composite materials. Especially, graphene-based semiconductor photocatalysts have attracted extensive attention because of their potential for solving environmental and energy problems. Graphene-based photocatalysts mainly show significant photocatalytic applications in four fields: Photocatalytic decomposition of organic pollutants, Photocatalytic splitting of H2O to produce hydrogen, Photocatalytic reduction of CO2 and Photocatalytic disinfection.
