| 英文摘要 | the silver catalyzed, selective catalytic reduction (scr) of nitrogen oxides (nox) by ch4, is shown to be a structure-sensitive reaction. pretreatment has a great affect on the catalytic performances. upon thermal treatment in inert gas stream, thermal induced changes in silver morphology lead to the formation of reduced silver species of clusters and particles. catalysis over this catalyst indicates an initially higher activity but lower selectivity for the ch4-scr of nox reaction induced restructuring of silver results in the formation of ill-defined silver oxides. this, in turn, impacts the adsorption properties and diffusivity of oxygen over silver catalyst, results in the decrease in activity but increase in selectivity of ag-h-zsm-5 catalyst for the ch4-scr of no..
