摘要
采用通用法制备了石墨烯负载超细硫化锌(ZnS-G)和石墨烯负载超细硫化镉(CdS-G)的复合物。通过扫描电子显微镜(SEM)、透射电子显微镜(TEM)、X射线衍射仪(XRD)、傅里叶变换红外光谱仪(FT-IR)等手段对样品进行了形貌观察和物相分析,并讨论了氧化石墨烯对复合物形貌的影响。研究结果表明,ZnS-G和CdS-G具有优异的光催化效果,氧化石墨烯用量为2%(wt,质量分数)条件下制得的ZnS-G,在紫外光照射50min,对甲基橙的降解率达到89.1%;氧化石墨烯用量为4%(wt,质量分数)条件下制得的CdS-G,在可见光照射100min,对甲基橙的降解率达到75.6%。
A general approach was developed to prepare graphene decorated ultra fine ZnS（CdS）（ZnS（CdS）-G）.Morphology was characterized via scanning electron microscopy（SEM）,transmission electron microscopy（TEM）,X-ray diffraction pattern（XRD）and fourier transform infrared spectrometer（FT-IR）.The effect of graphene oxide（GO）on the morphology of ZnS（CdS）-G was discussed.The water treatment results showed that ZnS-G and CdS-G had the excellent photocatalytic performance.When the GO mass fraction was 2 wt% and 89.1% of MO can be degraded under UV-light by ZnS-G in 50 min.When the GO mass fraction was 4 wt%,75.6% of MO can be degraded under visible-light by CdS-G in 100 min.
