石墨化氮化碳（g-C3N4）及其衍生物是光催化催化剂或载体的良好候选材料。由于它们通常是由单体在高温高压下聚合或缩合而成，因此开发一种具有成本效益的、基于溶液的低温生产方法非常重要。本文采用基于溶液的工艺，在氧化石墨烯和氰酰胺之间进行简单反应，制备了由g-C3N4和还原氧化石墨烯组成的新型杂化材料。在反应过程中，氧化石墨烯的还原和氧化石墨烯辅助生成g-C3N4同时发生。这些杂化物在太阳光照下表现出良好的光催化性能。(C) 2013 Elsevier Ltd.版权所有。
Graphitic carbon nitride (g-C3N4) and its derivatives are promising candidates as catalysts or supports for photocatalytic applications. Since they are typically produced by polymerization or condensation of monomers under high temperature and high pressure, development of a cost-effective, solution-based, low-temperature method of production is important. Herein, novel hybrid materials composed of g-C3N4 and reduced graphene oxide are produced using a simple reaction between graphene oxide and cyanamide using a solution-based process. During the reaction, reduction of graphene oxide and graphene oxide-assisted generation of g-C3N4 occurred simultaneously. These hybrids show good photocatalytic performance for the removal of organic dyes under one sun solar light illumination. (C) 2013 Elsevier Ltd. All rights reserved.
