Unraveling the Structural and Compositional Peculiarities in CTAB-Templated CeO-ZrO-MnO Catalysts for Soot and CO Oxidation.

Structure-performance relationships in functional catalysts allow for controlling their performance in a wide range of reaction conditions. Here, the structural and compositional peculiarities in CTAB-templated CeO-ZrO-MnO catalysts prepared by co-precipitation of precursors and their catalytic behavior in CO oxidation and soot combustion are discussed. A complex of physical-chemical methods (low-temperature N sorption, XRD, TPR-H, Raman, HR TEM, XPS) is used to elucidate the features of the formation of interphase boundaries, joint phases, and defects in multicomponent oxide systems.
