Effect of nature of ceria support in CuO/CeO2 catalyst for PROX-CO reaction

► CeO2-HT and CeO2-PP were presented as support on CuO/CeO2 catalysts for PROX-CO reaction. ► CuO/CeO2-HT catalyst presents best activity results at low temperature. ► Size particle and dispersion enhance the metal/support interaction.
