| 英文摘要 | iridium-carbon (ir-c) xerogels were synthesized via a one-pot sol-gel polycondensation of hexachloroiridic acid, resorcinol and formaldehyde, followed by carbonization in a nitrogen atmosphere at 500-1000 degrees c. the samples were characterized by various techniques including n-2 adsorption, xrd and tem. the n-2 adsorption showed that the ir-c samples were of microporous structures, and their specific surface areas increased with the pyrolysis temperature. both the xrd and tem revealed that the it particles in the ir-c samples were highly dispersed in the carbon matrix, in contrast with the large ir particles in the ir/c sample which was obtained by impregnation. the ir-c xerogels exhibited high activities and selectivities towards n-2 in the reduction of no with carbon or co. in particular, the ir-c samples behaved much stably than the ir/c, demonstrating the superiority of the one-pot synthesis method.
