| 摘 要： | 本实验以细鳞片石墨为原料,采用Hummers法制备氧化石墨,经超声波振荡得到氧化石墨烯,加入水合肼回流制得石墨烯材料。采用溶胶-凝胶法制备锐钛矿型TiO2及石墨烯/TiO2复合材料。在紫外光照射下,分别以石墨烯/TiO2复合材料及锐钛矿型TiO2为催化剂,在甲基橙溶液中进行光催化降解,结果显示,石墨烯/TiO2光催化性能明显高于相同条件下的锐钛矿型TiO2。

| Abstract: | In this experiment,30 mesh graphite was prepared as raw materials,Graphite oxide is prepared by Hummers method,and further treated with super-sonic oscillation to get grapheme oxide.After hydrazine hydrate was added,grapheme oxide was reduced to graphene by reflux.The anatase titanium dioxide and the composite of TiO2/graphene is prepared by sol-gel method.Under ultraviolet radiation,TiO2/graphene and TiO2 as catalyzers were added into methyl orange solution.The result shows that the activity of TiO2/graphene is better than that of TiO2 under the same conditions. |
