摘要:
通过煅烧法合成g-C3N4纳米片并在其表面负载Bi4MoO9纳米粒子(NPs),制备了Bi4MoO9/g-C3N4(BMC)异质结光催化剂. 采用TEM、SEM、DRS、PL等方法对BMC样品进行表征. 以磺胺二甲基嘧啶(SMT)为目标降解物,考察BMC的光催化性能. 结果表明,BMC-50(Bi4MoO9质量分数为50.0%)的光催化活性最高. BMC-50投加量为0.5 g·L-1时,SMT溶液在光照180 min后降解率可达94.0%,是单一Bi4MoO9降解能力的17.7倍. 复合材料中Bi4MoO9与g-C3N4间异质结构的构建降低了电子-空穴对的复合,提高了光催化性能.
Abstract:
g-C3N4 nanosheets are synthesized by polymerization method and loaded with Bi4MoO9 nanoparticles(NPs)on its surface to prepare Bi4MoO9/g-C3N4(BMC)heterostructure catalyst. BMC samples are characterized by TEM,SEM,DRS and PL. The photocatalytic performance of BMC is investigated with sulfadiazine(SMT)as the target degradation material. The results show that the photocatalytic activity of BMC-50(50.0% Bi4MoO9)is the highest. When the concentration of BMC-50 is 0.5 g·L-1,SMT could degrade 94.0% within 180 min,which is 17.7 times of the degradation capacity of Bi4MoO9. The fabrication of the heterostructure between Bi4MoO9 and g-C3N4 reduces the recombination of electron-hole pairs and enhances the photocatalytic performance.
