摘　　要：采用超声与水热相结合的方法制备一系列氮化碳/硅藻土/二氧化锰三元复合材料,结果表明:与纯g-C3N4相比,氮化碳/硅藻土/5%二氧化锰复合材料在降解盐酸四环中具有优异的光催化活性且材料在光催化反应过程中符合一级动力学过程。通过自由基捕获实验探究了反应过程中的主要活性因子为·O2-,同时提出了可能的催化机理。A series of g-C_(3) N_(4)/diatomite/MnO_(2) ternary composites were prepared by combining ultrasonic-hydrothermal methods.The results showed that the g_(3) N_(4)/diatomite/MnO_(2) composites exhibited better photocatalytic performance compared with pure g_(3) N_(4).The photocatalytic reaction process fitted with the first order kinetic process.The main activity species in the reaction was O_(2)-was explored by radical capture experiment and The possible catalytic mechanisms are also proposed.
