A strategy for a high dispersion of metal/metal oxide nanoparticles in a mono-modal fashion is developed. The key is the functionalization of mesopore walls with basic -C 3 H 6 -N + (Me) 3 (OH) − groups. The supported metal catalysts obtained in the present work exhibit high catalytic activities for CO 2 methanation at low temperature and CO oxidation. A strategy for achieving a high dispersion of metal and metal oxide nanoparticles in a mono-modal fashion is developed.
