Abstract

Supported nickel CHA-type zeolites with different framework compositions including borosilicate, gallosilicate and aluminosilicate were synthesized. The effect of heteroatoms in the framework on the state of the Ni species introduced was investigated. The size and dispersibility of the Ni species differed greatly depending on the heteroatom in the zeolite framework, and the use of the aluminosilicate-type framework led to the formation of a highly dispersed and nano-sized Ni species. Thus, prepared Supported Ni CHA-type aluminosilicate exhibited the highest catalytic performance in oxidative conversion of CH4.
