摘要
采用低温水热法,以四氯化钛为钛源,尿素为氮源,聚乙二醇(PEG-4000)为分散剂,在较低的水热温度下合成了高分散氮掺杂纳米二氧化钛/氧化石墨烯(GO)复合材料,利用XRD、TEM、FT-IR、Raman对合成样品的晶型、形貌及结构进行了表征。以染料亚甲基蓝为目标降解物,以可见光为光源,对样品的光催化活性进行评价。结果表明,用水热法合成的高分散氮掺杂纳米二氧化钛/氧化石墨烯复合材料表现出良好的光催化活性。
The highly dispersed N-doped titanium dioxide nanoparticles/graphene oxide composite material is prepared via a low temperature hydrothermal method,using four titanium chloride as the titanium source,urea as nitrogen source and polyethylene glycol（ PEG-4000） as dispersant. XRD,TEM,FT-IR and Raman are used to characterize the crystal form,morphology and strucdture of the obtained composite material. The photocatalytic activity of the sample is evaluated through the decomposition of the methylene blue solution under visible light irradiation. The results show that the highly dispersed N-doped nano titanium dioxide/graphene oxide composite exhibits excellent photocatalytic activity.
