摘要 以氧化石墨烯(GO)、钼酸、硫脲和TiN为原料,成功制备了MoS2/石墨烯/N-TiO2(MGNT)复合材料。利用X射线衍射仪(XRD)、扫描电子显微镜(SEM)、高分辨透射电子显微镜(HR-TEM)、X射线光电子能谱(XPS)及紫外-可见漫反射光谱(UV-Vis DRS)等手段测试分析了样品的物相组成、形貌、成分和光吸收性能。紫外-可见漫反射测试结果表明,MoS2、石墨烯共同修饰及氮掺杂使得TiO2的吸收带边发生红移,且其可见光吸收性能明显提高。可见光照射下降解亚甲基蓝溶液的实验结果表明,MoS2/石墨烯共同修饰的氮掺杂TiO2的光催化降解性能分别是氮掺杂TiO2(NT)和石墨烯修饰氮掺杂TiO2(GNT)的1.82倍和1.59倍,其吸附性分别为氮掺杂TiO2、石墨烯修饰氮掺杂TiO2的11.14倍和4.77倍。

Abstract: MoS2/graphene/N-TiO2 composites (MGNT) were prepared using GO, H2MoO4, (NH2)2CS, and TiN as the raw materials. The phase composition, morphology, chemical states of elements, and optical absorption performance were characte-rized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and ultraviolet-visible diffuse reflectance spectroscopy (UV-Vis DRS), respectively. An obvious red shift of absorption edge and enhanced intensity were observed for MGNT compared with N-TiO2(NT) and graphene/N-TiO2(GNT). The photocatalytic performance was evaluated via the photodegradation of methylene blue (MB) under visible light irradiation. The results showed that the photocatalytic performance of MGNT was 1.82 and 1.59 times of NT and GNT, respectively. In addition, the absorptivity of MGNT was 11.14 and 4.77 times of NT and GNT.
