Abstract Carbon black/ZnO nanocomposites have been successfully synthesized via a simple aqueous chemical growth method. The preparation of the carbon black/ZnO nanocomposites by adding an appropriate weight of carbon black to the ZnO growth process can be favorable to improve photocatalytic degradation of methyl blue under irradiation of ultraviolet light. Compare with commercial TiO2 and ZnO nanopowders, carbon black/ZnO nanocomposites can enhance the specific surface area, the light-harvesting ability, and the charge carrier separation for achieving highly efficient photocatalysts under irradiation of both ultraviolet and visible light. The carbon black/ZnO nanocomposites exhibited a low cost and sample approach, high reusability, and high visible-light-induced photocatalytic activity.

炭黑作为助催化剂的协同效应增强对 ZnO 纳米粒子的可见光光催化活性和稳定性

摘要 炭黑/ZnO 纳米复合材料已通过简单的水性化学生长方法成功合成。在ZnO生长过程中加入适量的炭黑制备炭黑/ZnO纳米复合材料有利于提高紫外光照射下甲基蓝的光催化降解。与商业 TiO2 和 ZnO 纳米粉相比，炭黑/ZnO 纳米复合材料可以提高比表面积、光捕获能力和载流子分离，从而在紫外和可见光照射下实现高效光催化剂。炭黑/ZnO 纳米复合材料表现出低成本和样品方法、高可重复使用性和高可见光诱导的光催化活性。
