Abstract
The oxide catalyst for the direct NO decomposition to N2 and 02 is deposited on the austenitic acid-proof steel substrate and contains the phase with aFe203 structure and the phase with spinel structure and the lattice parameters close to the lattice parameters of NiFe204. Those phases form the micro-crystallites that additionally contain Cr and Mn and eventually Si. The catalyst according to the invention is manufactured by the at least twice heating of the austenitc acid-proof steel substrate in the atmosphere containing oxygen, up to the temperature from the 600-850° C. range, with the rate of 2-6° C./min, followed by the annealing at that temperature for 2-6 hours.
