Theoretical and Experimental Chemistry Aims and scope

Abstract

Scanning electron microscopy, TPDA, XPE and IR spectroscopy were used to study the physicochemical indices of rhodium-promoted Rh-M x O y /ZrO2 oxide catalysts (M = Cr, Ce, Co). The enhancement of the redox properties of the oxide catalysts upon the introduction of rhodium does not alter their bifunctional nature in SCR activity; these catalysts have both redox and strong acid B-sites.
