| 英文摘要 | it was explored by density functional calculations that exchanged la or p species exert great influence on the local al sites as well as on the adjacent exchanged species. in partially exchanged la- or p/h-zsm-5 zeolite, some of the al sites will fall off from the zeolite framework even more easily than in h-form zsm-5, consistent with our xrf experiments. however, when exchanged by both la and p species, al at either of the two exchanged sites shows better stability compared to h-from. zeolite. la and p species will interact strongly with each other, as evidenced by the charge donation process and the shortening of p-o-1 bond length. it was just the cooperation of la and p species that enabled rscc catalysts worked normally under severe conditions.
