摘要

•A direct redox reaction was constructed between NO and SO2 for simultaneous removal.•The strategy minimized usage of other reductants/oxidants and reduced secondary pollution.•A unique SO2 adsorption route, SO2 disproportionation was triggered at La sites.•Oxidation state of Co had a critical effect on SO2 adsorption route and DeNOx activity.
