| 中文摘要 | it is well known that the porous structures of zeolites are very crucial for their shape selectivity in catalytic reactions. in this study, one- and two-dimensional hyperpolarized 129xe nmr spectroscopy has been used to characterize the porosity of catalytic materials, such as the identification of mesopores in ts-1/tihms micro/mesoporous composites and mesoporous zsm-5 zeolites, the connectivity of pores in co-crystallized mcm-49/zsm-35 zeolites, etc. the distribution of catalyst in the support can also be detected. examples are illustrated by metallic ga in mcm-41 and moo3 in hbeta zeolite and alumina composite support. additionally, the adsorption process of reactants in the zeolites can be traced by variable-temperature measurements |
