Graphene-Based Photo-Fenton Catalysts for Pollutant Control

摘要

Water pollution is a global environmental issue with multi-dimensional infl uences on human life.Some strategies,such as photo-Fenton reaction,have been employed to remove recalcitrant pollutants.Two-dimensional(2D)graphene and its threedimensional(3D)confi gurations have attracted considerable attention as emerging carbon-based catalysts in photo-Fenton fi elds owing to their alluring properties in electron transfer,reactant adsorption,and light response.This review summarizes the recent developments in 2D and 3D graphene-based catalysts for photo-Fenton reactions.Their structures,characteristics,activity,and mechanisms are discussed.The conclusions and outlooks are proposed for the profound understanding of challenges and future directions.
