CuO-Co3O4-CeO2 Ternary Oxide Catalyst with High CO Oxidation Capability Shows No Inhibition By Propene

A CuO-Co₃O₄-CeO₂ ternary oxide catalyst outperforms both our Pd/ZrO₂/SiO₂ catalyst and a commercial DOC catalyst for CO oxidation in simulated exhaust while showing no signs of inhibition by propene.   This catalyst has great potential as a low-cost component in automotive exhaust streams of advanced combustion engines with low temperature exhausts.
