摘要
通过热聚合法成功制备了g-C_(3)N_(4)-Nd复合催化剂,利用SEM、XRD、FT-IR和紫外-可见漫反射光谱仪等分析方法探究了其微观形貌、晶体结构和光催化特性。结果显示,g-C_(3)N_(4)-Nd复合催化剂展现出优异的光催化性能,当Nd负载质量分数为1.5%时,光催化降解效果最佳,其对盐酸四环素(TCH)的降解率从51.1%提升至68.5%。经过3次连续的降解试验验证,g-C_(3)N_(4)-Nd复合光催化剂具备优异的重复利用性能。
The g-C_(3)N_(4)-Nd composite catalyst is prepared by thermal polymerization,and its microstructure,crystal structure and photocatalytic properties are investigated using SEM,XRD,FT-IR,and UV-visible diffuse reflectance spectroscopy.The results show that the g-C_(3)N_(4)-Nd composite catalyst exhibits excellent photocata⁃lytic performance.When the mass fraction of loaded Nd is 1.5%,g-C_(3)N_(4)-Nd exhibits the optimal photocatalytic performance,increasing the degradation rate of TCH from 51.1%to 68.5%.After three consecutive degradation experiments,the g-C_(3)N_(4)-Nd composite photocatalyst has excellent reusability performance.
