Preparation of Husk-Based Porous Carbon-TiO2 Composites for Adsorption-Photocatalytic Degradation of Toluene in Aqueous Solution

摘要

In this study, PC-nanoTiO2 and PC-P25 were prepared via chemical-deposition and mixture-calcination methods, respectively. Both of PC-nanoTiO2 and PC-P25 were employed to adsorb and photocatalytic degrade toluene in aqueous solution. The characterization results show that distribution of TiO2 nanoparticles in PC-nanoTiO2 and PC-P25 were different, but their binding force between PC and TiO2 were both chemical bonds. Due to synergy of adsorption and photocatalytic degradation, both PC-nanoTiO2 and PC-P25 exhibit good effect in removing toluene in aqueous solution, and both PC-nanoTiO2 and PC-P25 could be utilized for treating wastewater generated from hazardous chemicals leakage accidents emergency.
