Abstract:
Carbonaceous catalysts are potential alternatives to metal catalysts. Graphene has been paid much attention for its high surface area and light weight. Here, hydrogenated graphene has been prepared by a simple gamma ray irradiation of graphene oxide aqueous suspension at room temperature. Transmission electron microscopic, element analysis, X-ray photoelectron spectroscopy, and UV-Vis spectrophotometer studies verified the hydrogenation of graphene. The as-prepared hydrogenated graphene can be used as a metal-free carbonaceous catalyst for the Fenton-like degradation of organic dye in water.

摘要:
采用室温辐照还原与氢化的方法制备氢化石墨烯. 透射电子显微镜、元素分析、X射线光电子能谱和紫外可见光谱等测试证实了获得的产物为氢化石墨烯. 以该氢化石墨烯为不含金属的催化剂进行了类Fenton反应,发现其有高的催化活性,可以用于水中有机物的氧化降解.
