In this study, cerium oxide with different exposed crystal facets was prepared and function as the support for MnO x /CeO 2 catalysts, whose catalytic performance were evaluated in the methanol oxidation reaction. The results showed that the difference in crystal facet exposure could remarkably affect the methanol oxidation performance of the MnO x /CeO 2 catalysts, where the (110) facet exposure is more beneficial to the catalytic performance. A series of characterizations revealed that the best performance of the MnO x /CeO 2 -NS catalyst can be attributed to the increase of oxygen vacancies and a more suitable valence state distribution, which is intrinsically correlated with the exposed (110) facet, resulting in excellent methanol oxidation performance with T 50 = 156 °C, T 90 = 171 °C, better stability and preferable H 2 O/CO 2 resistance. This work might provide a fundamental understanding for the rational design and optimization of manganese-cerium oxide catalysts for the methanol oxidation reaction.

Series of copper oxide supported on cerium oxide particles with different morphology (CuOx/CeO2-X) were fabricated and the catalytic performance (NO conversion, N2 selectivity, O2/H2O/SO2 resistance) were evaluated in NO+CO reaction....
