摘要 以石墨粉为原料,采用改进的Hummers法制取氧化石墨烯,利用化学还原法将银负载于石墨烯,并利用扫描电子显微镜(SEM)、X射线衍射仪(XRD)、傅里叶红外光谱仪(IR)、紫外-可见分光光度法(UV-Vis)对其进行表征。结果表明,柠檬酸钠成功地将银离子和氧化石墨烯还原,得到银负载石墨烯复合材料,银颗粒粒径范围为(10±6)nm。以甲基橙为目标降解物,探索其在可见光下的光催化性能、稳定性和回收率。实验结果表明,银负载量为100%时复合材料光催化性能最好、稳定性好、回收率较高。

Abstract: With graphite powder as raw material, graphene oxide is made by means of the modified Hummers method.Silver is loaded on the prepared graphene via chemical reduction method.And then the samples are characterized through scanning electron microscope (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and UV-Vis spectroscopy.The results show that silver ions and graphene oxide are successfully reduced by sodium citrate into silver-loaded graphene composites with the size of silver particles ranging from 4 nm to 16 nm.Methyl orange is used as the degradation target to explore the photocatalytic performance, stability and recovery rate of the samples under visible light.The experimental results show that the composite with a loading amount of silver being 100% has the best photocatalytic performance, the strongest activity and the higher recovery rate.
Key words:  silver loaded graphene    photocatalytic degradation    methyl orange
