Environment-friendly magnetic Fe-Ce-W catalyst for the selective catalytic reduction of NO with NH: influence of citric acid content on its activity-structure relationship.

The influence of the citric acid content on the structural and redox properties of a magnetic iron-cerium-tungsten mixed oxide catalyst prepared through a microwave-assisted citric acid sol-gel method is investigated TG-DTG-DSC, XRD, N adsorption-desorption, XPS, H-TPR and NH-TPD. Additionally, the NH-SCR activity of the magnetic FeCeW- ( = 0.25, 0.
