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. (C) 2008 Elsevier B.V. All rights reserved.
