Abstract: The 3D graphene based photocatalysts (GBP) are overviewed from three aspects of preparation,classification and basic function.The principles for 3D graphene helping its supported catalysts to separate electron-hole efficiently,widen the light absorption range and improve adsorption against pollutants are analyzed.In addition,the important influences of the graphene substrate with chemically-doped N and B atoms on the catalytic performance of 3D GBP are overviewed.
