| 英文摘要 | the catalytic performance of silver-modified zsm-5 catalysts in the selectively catalytic reduction (scr) of nox with methane was investigated. no was selectively reduced by ch4 to n-2 in the presence of excess o-2, and the catalytic activity depended on both the activation of ch4 and the adsorption properties of nox. silver incorporated in zsm-5 zeolite activated ch4 at low temperatures and lowered the "light-off" temperature for the ch4-scr of nox. temperature-programmed (tp) spectroscopy studies depicted that surface nitrosyl species directly decomposed to n-2 in the absence of o-2. ch4 could not effectively reduce surface nitrosyl species, but might facilitate the direct decomposition of no through the removal of surface oxygen. surface nitrates were formed in no and o-2 coexisting system and could be effectively reduced by cr4 to nitrogen. the priority of surface nitrates to o-2 in the reaction with ch4 clearly demonstrated that ch4 selectively and preferentially reduced the surface nitrate species to n-2 in the excess of oxygen.
