| 摘 要： | 以氯化铜（CuCl2·2H2O）、硫脲（（NH2）2CS，Tu）、1，2-丙二醇（1，2-PG）、氯化铁（FeCl3·6H2O）及氧化石墨烯（GO）为原料，通过溶剂热法制备了具有可见光活性的Fe-CuS/RGO复合材料。采用XRD、SEM、TEM、Raman、XPS、TG、UV-Vis等手段对产品进行了表征，并以亚甲基蓝（MB）为目标降解物对其可见光催化活性进行了研究。光催化结果表明：在汞灯（150 W）下照射140 min，CuS、CuS/RGO和Fe-CuS/RGO对MB的脱色率分别为41.2%、81.5%和90.6%。Fe-CuS/RGO对MB的降解效率较CuS/RGO和CuS有较大提升，可能原因是Fe元素有利于电荷在CuS与RGO界面间传输，降低了光生电子-空穴对的复合几率，进而提高了光催化活性。

| Abstract: | The Fe element doped CuS/RGO(Fe-CuS/RGO) was fabricated via a facile one-step solvothermal method, which displayed outstanding photocatalytic activity for methylene blue(MB) degradation. The composition and structure of the prepared composites were characterized by X-ray diffraction(XRD), X-ray photoelectron spectroscopy(XPS), Raman spectra, photoluminescence(PL) spectra, scanning electron microscopy(SEM), Transmission electron microscope(TEM) and UV-Vis optical absorption spectroscopy. The results showed that pristine CuS, CuS/RGO and Fe-CuS/RGO exhibited photocatalytic activity for the photodegradation of MB with degradation efficiency of 41.2%, 81.5% and 90.6%, respectively, in 140 min under mercury lamp irradiation, indicating that Fe-CuS/RGO could be acknowledged as a promising photocatalyst for the removal of organic contaminants. The enhanced photocatalytic activity was ascribed to that Fe element could be acted as an interfacial charge transfer channel between CuS and RGO to thus inhibit the recombination of photogenerated electron-holes pairs. |
