Tungsten‐doped foam g‐C 3 N 4 with improved photocatalytic properties for degradation of pollutant and hydrogen evolution

Abstract As a potential material applied in the photocatalytic field, graphitic carbon nitride (g‐C 3 N 4 ) has attracted extensive attention for its advantages of visible‐light response, excellent thermodynamic, and chemical stability. However, the photocatalytic performance of g‐C 3 N 4 is still limited in practical applications. Here, using a facile thermal polymerization method, unique W‐doped foam g‐C 3 N 4 was synthesized to realize enhanced photocatalytic performance for the degradation of Rhodamine B and the evolution of hydrogen. Compared with pure foam g‐C 3 N 4 , tungsten doping modified the foam g‐C 3 N 4 and efficiently improved its specific surface area, leading to enhanced photocatalytic performance. The average rate of hydrogen evolution was as high as 8818 μmol·h −1 ·g −1 , which was better than most photocatalysts. This work proposes a new effective method and idea to modify g‐C 3 N 4 for improving its photocatalytic performance.
