Reduced graphene oxide (RGO) coated with ZnO nanoparticles (NPs) was synthesized by a self-assembly and in situ photoreduction method, and then their application for removing organic pollutant from water was investigated. The RGO@ZnO composite nanomaterial has unique structural features including well-dispersed NPs on the surface and dense NPs loading. This composite exhibited a greatly improved Rhodamine B (RhB) adsorption capacity and an improved photocatalytic activity for degrading RhB compared to neat ZnO NPs. These properties made RGO@ZnO reusable for pollutant adsorbent. The composite showed an excellent cycling performance for organic pollutant removal up to 99% recovery over several cycles via simulated sunlight irradiation.
通过自组装和原位光还原法合成了负载氧化锌纳米粒子（NPs）的还原氧化石墨烯（RGO），并研究了其在去除水中有机污染物方面的应用。RGO@ZnO 复合材料具有独特的结构特征，包括 NPs 在表面的良好分散和 NPs 的密集负载。与纯 ZnO NPs 相比，该复合材料对罗丹明 B（RhB）的吸附能力显著提高，光催化降解 RhB 的活性也得到提高。这些特性使 RGO@ZnO 成为一种可重复使用的污染物吸附剂。该复合材料在模拟太阳光照射下，通过几个循环的吸附-脱附实验，对有机污染物的去除率高达 99%，表现出了优异的循环性能。
