本文借助ESCA技术,表征了在氧化—还原循环的不同阶段,NiZSM-5沸石的表面特性,探讨了该类沸石上镍物种氧化—还原的可逆性。
In this paper, the ESCA technique was used to characterize the surface properties of NiZSM-5 zeolites at different stages of the oxidation-reduction cycle. The reversibility of the oxidation-reduction of nickel species on the zeolites was also discussed.
