Graphene/CuS Microflower and Graphene/SnS Microflower Prepared by General Method and Its Application in the Water Treatment

以L-组氨酸辅助和微波加热相结合,得到了石墨烯/硫化铜微米花和石墨烯/硫化亚锡微米花的通用制备技术。通过扫描电子显微镜(SEM)、透射电子显微镜(TEM)、X射线衍射分析(XRD)、傅里叶变换红外光谱仪(FTIR)、X光电子能谱(XPS)等手段对样品进行了形貌观察和物相分析,并阐明了获得石墨烯/硫化铜花瓣和石墨烯/硫化亚锡花瓣的形成机理。对其光催化性能的研究结果表明,在可见光照射下,石墨烯/硫化铜花瓣和石墨烯/硫化亚锡花瓣能够降解溶液中83.5%(40 min内)和90.4%(50 min内)的甲基橙,表现出优异的可见光催化效果。

One general method was developed for the synthesis of graphene-Cu S microflower and graphene-Sn S microflower.Morphology was characterized via scanning electron microscopy(SEM),transmission electron microscopy(TEM),X-ray diffraction pattern(XRD),fourier transform infrared spectrometer(FTIR),X-ray photoelectron spectroscopy(XPS).The formation mechanism was analyzed.The photocatalytic test showed that 83.5%and 90.4%of MO was degraded by graphene-Cu S microflower(40 min)and graphene-Sn S microflower(50 min)under visible light,indicating that the excellent photocatalytic efficiency could be obtained.
