Khảo sát tính chất hấp phụ và xúc tác quang của tổ hợp ống nanotitan oxit và graphene oxit

This study synthesizes graphene oxide (GO) by modified low temperature Hummer’s method and in-situ hydrothermally grown TiO2 nanotube (TNT) on GO sheet. Transmission electron microscopic (TEM) images show 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 diffraction pattern of GO indicates the successful fabrication. The UV-vis measurement with methylene blue indicates the improvement of physical adsorption and photocatalytic activity of the composite samples.
