利用正电的锌金属离子与超声剥离制备出带负电的氧化石墨烯,在水-乙醇混合介质中通过静电自组装将ZnO纳米颗粒与氧化石墨烯复合,成功制备ZnO/GO复合催化剂;再利用水热法将Fe2O3负载到ZnO/GO复合催化剂上,得到了全固体Z-Scheme光催化剂Fe2O3/RGO/ZnO。选用甲基橙测试材料的光催化性能,结果发现Fe2O3/RGO/ZnO具有最好的光催化性能。
This article utilized negatively charged graphene oxide prepared by ultrasonic peeling with positively charged zinc metal ions in water-ethanol mixed medium to combine ZnO nanoparticles with graphene oxide (GO) through electrostatic self-assembly to obtain ZnO/GO composites catalyst.Using hydrothermal method to load Fe2O3 into ZnO/GO composite catalyst,an all-solid Z-Scheme photocatalyst Fe2O3/RGO/ZnO was obtained.Methylene orange was used to test the photocatalytic performance of the material,and the results showed that Fe2O3/RGO/ZnO had the best photocatalytic performance.
