二氧化钛/氧化石墨烯复合光催化剂的合成
Synthesis of the titania/graphene oxide composite photocatalyst
摘要
Abstract
A series of titania/graphene oxide (TiO2/GO) composite photocatalysts with different mass fractions of graphene oxide were prepared in an aqueous system by hydrothermal method,using tetrabutyl titanate and graphene oxide as starting raw materials. FE-SEM results show that the TBOT is adsorbed on graphene oxide surface in multimolecular layer,and finally transformed into anatase TiO2 during hydrothermal process. When the mass fraction of graphene oxide is below 3%,the product photocatalyst consists of pure TiO2 and TiO2/GO composite. As the graphene oxide content exceeds 5%,the product consists of only TiO2/GO composite. The results of electrochemical measurement indicate that the carrier transport efficiency in TiO2 electrode increases after TiO2 is combined with GO. As the mass fraction of graphene oxide reaches 10%,the composite photocatalyst shows the highest photocatalytic activity for methylene. The photocatalytic activity can be further greatly enhanced after the bound graphene oxide is reduced to graphene.关键词
