AbstractMalodor is an important class of air pollution that poses a serious threat to personal health and quality of life. Ammonia gas is a major cause of malodor complaints and is produced by microbial decompositions of organic wastes. A catalyst capable of attaining better than 99 % conversion of 50 ppm NH3 in air at room temperature was successfully prepared. The EA of the reaction is dramatically decreased by using the catalysts when the ratio of VOx/TiOx increases. The NH3 was oxidized to nitrogen and water during the reaction without producing NOx. The catalyst was characterized by BET, micro-Raman and X-ray photoelectron spectroscopy to identify the active sites to be monomeric VOx on TiOx.
