摘要：

Porosity control: Mixed metal oxides (CuM/CeO2, M=Co, Fe) with tailored porosity were prepared by improved hard templating. These materials were highly active and selective catalysts for low-temperature oxidation of CO in the presence of excess H2 (see picture), a process which is central for the practical use of H2 in proton-exchange membrane fuel cells.
