Effect of the Growth of Nano-Sized Pd Particle in 1 wt% Pd/γ-Al2O3 Catalyst on the Complete Oxidation of Volatile Organic Compounds

The effect of growth of nano-sized Pcl particle on the catalytic activity of 1 wt% Pd/gamma-Al2O3 catalyst were examined to obtain the complete oxidation of volatile organic compounds (VOCs: toluene, xylene). Fresh and used forms of 1 wt% Pd/gamma-Al2O3 catalysts were characterized by using X-ray photoelectron microscopy (XPS), Transmission electron microscopy (TEM), and Brunauer Emmett Teller (BET) surface area analyses. Catalytic activity tests revealed that the conversion of VOCs increased with the lapse of reaction time at certain reaction temperature. The results of the instrumental analyses and the catalytic performance indicated that the conversion of VOCs was highly dependent on the growth of nano-sized Pcl particle in the catalyst.
