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

Abstract:

nanosized 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 nanosized 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 nanosized 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 nanosized TiO₂/GACs composite have the best effect of removal methylene blue,the rate up to 97.0 % in 180 min.
