微波法制备银镁共掺氧化锌复合光催化剂及其光催化性能研究

采用环形聚焦单模微波辅助法（简称微波法）快速合成银镁共掺氧化锌复合光催化剂（简称复合光催化剂），并运用X射线衍射、扫描电子显微镜对其结构和形貌进行表征。将此复合光催化剂应用于光催化降解罗丹明B和含油污水，研究其光催化性能并探究光催化降解机理。结果表明：微波法合成的复合光催化剂具有良好的光催化性能，对含油污水的降解率优于商用二氧化钛；复合光催化剂重复使用4次后罗丹明B的降解率仍维持在92%以上，化学稳定性良好。。

MICROWAVE-ASSISTED SYNTHESIS OF SILVER-MAGNESIUM CO-DOPED ZINC OXIDE AND ITS PHOTOCATALYTIC PERFORMANCE

A ring-focusing single-mode microwave synthesis method was used to rapidly synthesize a composite photocatalyst of silver-magnesium co-doped ZnO. XRD and SEM were used to characterize the structure and morphology of the synthesized photocatalyst. The photocatalytic degradation of Rhodamine B and oily wastewater by the photocatalyst was investigated. The performance and the mechanism of the reactions were explored. The results showed that the composite photocatalyst synthesized by microwave method had a good photocatalytic performance, and the degradation rate for oily wastewater was better than that of commercial titanium dioxide. After four cycles, the degradation rate of Rhodamine B was still above 92%, indicating that its chemical stability was good.
