Photocatalytic removal of VOCs in humid condition using Pd/TiO2 coated annular photocatalytic reactor
Abstract
This study reports preparation, characterization and photocatalytic activity of nano Pd/TiO2 catalyst for removal of VOCs in humid conditions. Different Pd/TiO2 samples were prepared with Pd content ranging from 0.3 to 1wt%. Wet impregnation and metal-sol were applied for Pd/TiO2 preparation. The catalysts were used in a coated annular photocatalytic reactor for removal of VOCs in highly humid condition by a photocatalytic process. By this photocatalytic process, the maximum toluene removal efficiency was 63% (wet impregnation) and 85% (sol-metal) in the case of initial toluene concentration of 314 ppm and relative humidity of 60%.
