采用水热法制备了一系列g-C3 N4-Sb 2S 3/Sb 4 O 5Cl 2（SCL-CX）复合光催化剂。采用TM 3000、粉末X射线衍射（XRD）、X射线光电子能谱（XPS）和紫外-可见漫反射光谱（UV-vis DRS）对材料进行了表征。该光催化剂的光催化活性高于纯的g-C3 N4、Sb 4 O 5Cl 2和Sb 2S 3/Sb 4 O 5Cl 2（SCL）。在可见光下，170 mg g-C3 N4质量的复合材料在60 min内对橙子（MO）的光催化降解率可达95%以上，其光催化性能的提高归因于可见光区较强的吸收和更有效的电子-空穴分离。(C)2015 Elsevier B.

A series of g-C3N4-Sb2S3/Sb4O5Cl2 (SCL-CX) composite photocatalysts were successfully prepared via a hydrothermal method. The as-prepared materials were characterized by TM3000, powder X-ray diffraction (XRD), X-ray Photoelectron Spectroscopy (XPS) and UV-vis diffuse reflectance spectra (UV-vis DRS). The obtained photocatalyst showed higher photocatalytic activity than pure g-C3N4, Sb4O5Cl2 and Sb2S3/Sb4O5Cl2 (SCL). The optimum photocatalytic of the composite with the mass of 170 mg g-C3N4 and a degradation efficiency up to 95% for methyl orange (MO) under visible light was achieved within 60 min. The enhanced photocatalytic performance could be attributed to the stronger absorption in the visible region and the more efficient electron-hole separation. (C) 2015 Elsevier B.V.
