Abstract

Abstract: The activity of the MnO2-CeO2/Zr0.25Ti0.25Al0. 5O1.75 monolith catalyst for selective catalytic reduction of NO by NH3 decreased with the increase of calcination temperature. The catalytic activity was significantly related to the specific surface area, oxygen storage capacity, and surface acid amount of the catalyst.

Key words: calcination temperature, selective catalytic reduction, nitrogen oxide, manganese dioxide, ceria, monolith catalyst
