Highly monodisperse supported metal nanoparticles by basic ammonium functionalization of mesopore walls for industrially relevant catalysis

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.
