摘　　要：以两步水热法制备了Bi_(2)MoO_(6)/C_(3)N_(4)/ZnO复合材料,在光压条件下,以氨氮为目标降解物评价了复合材料的压电-光催化性能。同时采用FTIR、SEM、UV-vis等方法进行形貌分析和光化学性能测试。结果表明:Bi_(2)MoO_(6)/C_(3)N_(4)/ZnO复合材料的降解率相较于C_(3)N_(4)/ZnO和ZnO有所提升,且三元复合材料的降解速率常数是C_(3)N_(4)/ZnO的3.2倍,是ZnO的9.7倍。此外,重复利用实验和普适性实验结果表明:Bi_(2)MoO_(6)/C_(3)N_(4)/ZnO复合材料具有良好的光催化性能和稳定性。Bi_(2)MoO_(6)/C_(3)N_(4)/ZnO composites were prepared by two-step hydrothermal method,and the piezo-photocatalytic performance of the composites was evaluated under piezo-photocatalytic conditions with ammonia nitrogen as the target pollutant.The morphological analysis and photochemical property test were also carried out by FTIR,SEM and UV-vis.The results showed that the degradation rate of Bi_(2)MoO_(6)/C_(3)N_(4)/ZnO composites was enhanced compared with C_(3)N_(4)/ZnO and ZnO;and the degradation rate constant of the ternary composites was 3.2 times higher than that of C_(3)N_(4)/ZnO,and 9.7 times higher than that of ZnO.In addition,reuse experiment and generalization experiment results showed that the Bi_(2)MoO_(6)/C_(3)N_(4)/ZnO composites had good photocatalytic performance and stability.
