可见光催化剂激发了巨大的研究努力。本文采用一种简单的方法制备了类石墨烯Co3S4纳米片/Ag2S纳米复合材料，并用透射电子显微镜、X射线衍射仪、紫外可见光谱等手段对其进行了表征，并通过可见光照射下对亚甲基蓝(MB)和甲基橙(MO)的光催化降解来评价其光催化性能。与纯Co3S4纳米片或Ag2S纳米颗粒相比，纳米复合光催化剂表现出优异的稳定性和光催化活性。其优异的光催化性能归功于其独特的结构，可以有效地促进电子/空穴的分离和传输。(C)2015爱思唯尔B.V.保留所有权利。
Visible light photocatalysts have stimulated great research efforts. In this contribution, graphene-like Co3S4 nanosheet/Ag2S nanocomposite was prepared using a simple method, and characterized by transmission electron microscopy, X-ray diffraction, and UV-Vis DRS, etc. The photocatalytic properties of the nanocomposite was evaluated by the photocatalytic degradation of Methylene blue (MB) and Methyl orange (MO) under visible light irradiation. The nanocomposite photocatalyst displays excellent stability and photocatalytic activity compared with pure Co3S4 nanosheet or Ag2S nanoparticles. The superior photocatalytic properties were attributed to its unique structures, which could promote efficiently electron/hole separation and transportation. (C) 2015 Elsevier B.V.
