Preparation of Nano-sized TiO2 Supported on Granular Activated Carbon and the Photocatalytic Degradation of Methylene Blue

摘要：

Nano-sized TiO2 were prepared using TiOSO4 as the precursor by hydrolysis-precipitation and hydrothermal method. Through dipping granular activated carbon (GAC) into the TiO2 hydrosols, The nano-sized TiO2/GACs composite was obtained. The surface morphology, microstructure and element distribution of the composite were characterized by TEM, SEM, XRD, EDS respectively. The results show that the synthesized nano-sized TiO2 is anatase phase with average size of 150-200 nm and can be dispersed uniformly on the surface of GACs. Photocatalytic experimental shows that when the load amount is 1.5％, the nano-sized TiO2/GACs composite have the best effect of removal methylene blue,the rate up to 97.0 ％ in 180 min.
