Adsorption Property and Photocatalytic Activity of Sol-Gel Prepared Porous TiO₂ Using PEG1000 as Template

Abstract:

PEG1000 was used as a template to prepare porous TiO2 photocatalyst through sol-gel process. The amount of PEG1000 and calcination temperature and time were studied with respect to porous TiO2 activity. At the optimum adding amount of PEG1000, 30.0% of the initial methyl orange was degraded. Methyl orange adsorption on the porous TiO2 maintained less than 2% during the whole template content range. During the calcination temperature range from 400 oC to 600 oC and time range from 2 h to 5 h, the optimum degradation activity appeared to the sample calcinated at 500 oC for 4 h. Adsorption of the materials had no variation at different calcination temperatures and times, and was quite weak compared with degradation efficiencies. 96.2% of the initial methyl orange was degraded after 100 min of irradiation.
