Highly efficient cerium dioxide nanocube-based catalysts for low temperature diesel soot oxidation: the cooperative effect of cerium- and cobalt-oxides

Abstract

Co₃O₄ promoted CeO₂ nanocubes exhibit a remarkable catalytic activity for soot oxidation, attributed to the superior reducible nature of CeO₂ and the preferential exposure of CeO₂ (100) and Co₃O₄ (110) facets.
