| Research Abstract |
Improvement of catalytic activity for reduction of nitrogen oxides (NOx) by urea as useful method of NO_x removal from diesel exhausts. This study showed that addition of H_2 in the selective catalytic reduction of NO by urea caused an drastic improvement of catalytic activity of silver-alumina. The mechanism and structure of active species in the present reaction system were studied by kinetic and spectroscopic studies. Ag clusters formed via H_2 addition are shown to be the reactive species.
