Functionalized graphene sheets (FGS)/ZnO nanocomposites were fabricated via thermal treatment method, using graphene oxide as a precursor of graphene, Zn(NH(3))(4)CO(3) as a precursor of zinc oxide, and poly(vinyl pyrrolidone) as an intermediate to combine zinc with carbon materials. Thermogravimetric analysis, X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, transmission electron microscopy (TEM), and scanning electron microscopy (SEM) were used to characterize crystal structure and morphology of FGS/ZnO nanocomposites. It was shown that the well-dispersed ZnO nanoparticles were deposited on FGS homogeneously. The composites exhibited photocatalytic activity to decompose rhodamine 6G efficiently under low-power ultraviolet (UV) light. This facile and low-cost method makes the composite a perfect candidate in applications of catalysis and other areas.
功能化石墨烯片（FGS）/氧化锌纳米复合材料是通过热处理方法制备的，使用氧化石墨烯作为石墨烯的前体，Zn(NH(3))(4)CO(3)作为氧化锌的前体，聚（乙烯基吡咯烷酮）作为连接锌和碳材料的中间体。热重分析、X 射线衍射（XRD）、傅里叶变换红外（FTIR）光谱、透射电子显微镜（TEM）和扫描电子显微镜（SEM）用于表征 FGS/氧化锌纳米复合材料的晶体结构和形态。结果表明，均匀地沉积在 FGS 上的 ZnO 纳米粒子具有良好的分散性。该复合材料在低功率紫外（UV）光下表现出高效分解罗丹明 6G 的光催化活性。这种简单且低成本的方法使得该复合材料在催化等领域的应用中具有很大的潜力。
