摘要
Graphene oxide (GO) was prepared using a modified Hummers method with flake graphite as raw materials, then the graphene oxide/titanium dioxide (GO/TiO2) was synthesized through a in situ sol-sel method using tetrabutyl titanium as Ti source, and themally reduced graphene oxide/TiO2 composite photocatalyst was prepared by annealing under inert atmosphere. The photocatalyst was characterized by FT-IR, XRD, Raman, SEM, TEM and UV-Vis spectrophotometry. The photocatalytic degradation of methyl orange using the photocatalyst was studied. The results showed that the main phase of products is antase TiO2, the TiO2 nanoparticles with the diameter about 15 nm attached on the surface of reduced graphene oxide matrix and formed a layer of dense TiO2. The composite photocatalyst exhibited a excellent photocatalytic property under visible light region. ©, 2015, Journal of Functional Materials. All right reserved.
