Experimental research on catalytic decomposition of nitrous oxide on supported catalysts

A series of Ni–Co catalysts were prepared in this study. Experimental results showed that supported Ni–Co catalyst had the ability of decomposition of N2O, and its activity was increased with increasing content of the catalytic components on the support. Study indicated that a little addition of platinum catalytic component to the Ni–Co catalyst would benefit on improving its activity, and it was obvious under lower reaction temperature. Experimental results showed that the Pt–Ni–Co catalyst had good stability. XRD, SEM, TG and ICP characterization also showed that the prepared catalyst had a good stable structure before and after reaction.
