Tungsten‐doped foam g‐C3N4 with improved photocatalytic properties for degradation of pollutant and hydrogen evolution

As a potential material applied in the photocatalytic field, graphitic carbon nitride (g‐C3N4) has attracted extensive attention for its advantages of visible‐light response, excellent thermodynamic, and chemical stability. However, the photocatalytic performance of g‐C3N4 is still limited in practical applications. Here, using a facile thermal polymerization method, unique W‐doped foam g‐C3N4 was synthesized to realize enhanced photocatalytic performance for the degradation of Rhodamine B and the evolution of hydrogen. Compared with pure foam g‐C3N4, tungsten doping modified the foam g‐C3N4 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‐C3N4 for improving its photocatalytic performance.
