| 英文摘要 | a series of dual-metal zeolitic imidazolate framework (zif) crystals with sod and rho topologies was synthesised by metal substitution from zif-108 (zn(2-nitroimidazolate)(2), sod topology) as the parent material. this was based on the concept that metal substitution of zif-108 requires a much lower activation energy than homogenous nucleation owing to the metastability of zif-108. in-depth investigations of the formation processes of the daughter zifs indicated that the transformation of zif-108 is a dissolution/heterogeneous nucleation process. typical isostructural co2+ substitution mainly occurs at the outer surface of zif-108 and results in a core-shell structure. on the contrary, the cu2+-substituted zif has a rho topology with a homogeneous distribution of cu2+ ions in the structure. substitution with ni2+ resulted in a remarkable enhancement in adsorption selectivity toward co2 over n-2 by a factor of up to 227. with co2+-substituted nanoparticles as inorganic filler, a mixed matrix membrane based on polysulfone displayed greatly improved performance in the separation of h-2/ch4, co2/n-2 and co2/ch4. |
