Abstract:
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 -C3H6-N+(Me)3(OH)- groups. The supported metal catalysts obtained in the present work exhibit high catalytic activities for CO2 methanation at low temperature and CO oxidation.
