载Ni沸石(A,X,Y和M型)上Ni~(2+)的还原表明,沸石性质对Ni~(2+)的可还原性和Ni~0的分散度有明显影响,后者与载Ni沸石的催化性质密切相关.但是,对沸石结构与Ni~(2+)的可还原性和Ni~0分散度之间的关系迄今仍不清楚. 本文通过几种载Ni沸石(Y,M和ZSM-5型)上Ni~(2+)还原和Ni~0分散度的研究,观察沸石结构对它们的影响,并借助ESCA技术研究了NiNaY的还原试样在不同处理条件下表 The reduction of Ni 2+ on Ni-loaded zeolites (A, X, Y and M) shows that zeolite properties have a significant effect on the reducibility of Ni 2+ and the dispersion of Ni 0, Is closely related to the catalytic properties of Ni-loaded zeolites.However, the relationship between the zeolite structure and the reducibility of Ni 2+ and the dispersion of Ni ~ 0 remains unclear.Therefore, , M and ZSM-5), and the effects of zeolite structure on them were investigated. The ESCA technique was used to study the reduction of NiNaY samples under different treatment conditions
