In Situ Preparation and Analysis of Bimetal Co-doped Mesoporous Graphitic Carbon Nitride with Enhanced Photocatalytic Activity

Co/Mo co-doped mesoporous graphitic carbon nitride (g-C3N4) exhibited enhanced photocatalytic performances with regard to H2 generation (8.6 times) and Rhodamine B degradation (10.1 times) compared with pristine g-C3N4. The density functional theory calculations and optical simulation illustrate that Co/Mo co-doping and the created mesoporous structure can enhance light absorption. The enhanced activity depends on the synergistic effect of Co and Mo co-doping.
