答案

问题太多了了,你不如把中文写出来我帮你翻译.
翻译如下,请审阅.Since entering the 21 Century,the research of scientific researchers on photocatalytic performance has entering a new era,the emergence of double compounds attracts the attention from more and more researchers.The sulfur/molybdenum disulfide double compound introduced in this paper is one of them.It uses Na2MoO4•2H2o and C2H5NS as the raw materials,and applies solvent thermal synthesis method to prepare sulfur/molybdenum disulfide double compound under the condition without adding any surfactant or end capping reagent.The prepared sulfur/molybdenum disulfide double compound is characterized by various methods,such as UV-Vis diffuse reflectance (DRS),transmission electron microscope (TEM),fluorescence spectroscopy (PL),X ray powder diffraction(XRD) ,X ray photoelectron spectroscopy (XPS) ,etc.Furthermore,the UV and visible light degradation activity of the sulfur/molybdenum disulfide double compound is studied taking methylene blue (MB) as the degradation object.The results show that,compared with the pure sulfur,sulfur/molybdenum disulfide double compound exhibits better UV and visible light MB degradation activity.
