摘要 通过高温热解三聚氰胺制备石墨相氮化碳,利用表面沉积法将硝酸铁与氮化碳复合形成FeCN复合材料,再利用水热法合成不同FeCN含量的FeCN/Bi2WO6复合材料体系并进行了光催化降解实验,对FeCN的掺杂量及光催化机理进行了分析.结果表明,复合材料FeCN成功掺杂到FeCN/Bi2WO6中,并形成层片颗粒结构且明显提高了光催化性能,FeCN掺杂量60%的条件下所得复合材料对甲苯的光催化降解率可达86%.机理分析表明,光催化降解甲苯的过程中·O2^-起到重要作用. Graphite phase carbonitride was prepared by pyrolysis of melamine at high temperature.The FeCN composite was synthesized by surface deposition method.The FeCN/Bi 2WO 6 composite system with different FeCN content was synthesized by hydrothermal method.The photocatalytic degradation experiments were carried out to analyze the doping amount and photocatalytic mechanism of FeCN.The results show that the composite FeCN was successfully doped into the FeCN/Bi 2WO 6 system, and the layered particle structure was formed and the photocatalytic performance was improved.The light of the composite toluene prepared under the condition of FeCN doping amount of 60% was obtained.The catalytic degradation rate can reach 86%.The mechanism analysis further shows that ·O2^- plays an important role in the photocatalytic degradation of toluene.
