Effect of Ce Addition on MgAl Mixed Oxides for the Total Oxidation of CO and Toluene

Résumé

VOC and CO constitute the principal emission during cold-start of vehicles. In order to decrease this emission at low temperature, this study focuses on the development of new catalysts: MgAlCe mixed oxides issued from the calcination of hydrotalcite precursors. Addition of cerium on the MgAl solid increase the reducibility of catalysts inducing a better catalytic reactivity for the CO and toluene total oxidation. Moreover, toluene oxidation is facilitated at low temperature due to a beneficial effect of CO in the reaction mixture.
