Physical Adsorption and Photocatalytic Activity of Titanium Dioxide Nanotube and Graphene Oxide Composite

Abstract

In this study, we synthesized graphene oxide (GO) by modified low temperature Hummer’s method and in situ hydrothermally grown TiO­2 nanotube (TNT) onGO sheet. Transmission electron microscopic (TEM) images showed the homogeneous formation of TNT with the mean diameter of ~8 nm and the co-existence of TNT and GO in the composite sample. X-ray differaction pattern of GO indicated the successful fabrication. The UV-vis measurement with methylene blue indicated the improvement of physical adsorption of the composite samples.
