Abstract

A catalyst for direct decomposition removal of NOx from an exhaust gas stream to N2 and O2, the catalyst comprising a dual dispersed supported metal oxide material, which comprises MOx-CuOx dispersed on a CO3O4 spinel oxide support, wherein M is selected from the group consisting of Zn, Ce, Mg, Tb, and Gd. The dual dispersed supported metal oxide catalysts have good activity and selectivity for N2.
