Study on Environmental Materials with Pore Size and Photocatalytic Activity of Porous TiO₂-Al₂O₃ Photocatalyst

Abstract:

A novel porous TiO₂-Al₂O₃ composite as a kind of environmental material was prepared by sol-gel method. The pore size distribution is not even in the whole pore size range. When pore size is 7.049 nm, the maximum pore volume of the material is 0.06627 cm³·g^-1. The average pore size for the material is 14.56 nm and the total pore volume is 0.3945 cm³·g^-1, as calculated from BJH method. Photocatalytic degradation of methyl orange can be regarded as following first order kinetic reaction. After 90 min of reaction, methyl orange degradation on the material was 77.0% and the total dye decoloration rate was 95.1%, containing both adsorption and photocatalytic degradation. The intensities of both peaks in visible and UV regions decreased sharply during photocatalytic degradation process.
