Abstract
In this paper, we designed and prepared the polymeric carbon nitride‐supported tungsten (W@PCN) materials. They were employed as the catalysts for photocatalytic oxidation of aniline in water. During the process, H 2 O 2 was initially generated via the PCN‐catalyzed hydrophotolysis. Catalyzed by supported tungsten, aniline was oxidized by the in situ generated H 2 O 2 to obtain less toxic polyaniline. It was found that by using KBr as the additive, the highly crystalline K‐intercalated material (W@PCN‐K) could be prepared. Catalytic activity of the material was obviously enhanced due to its improved surface morphology with elevated specific surface areas. The novel highly crystalline K‐intercalated material is expected to be applied in waste water treatment for its superior catalytic performances.
