Abstract:
Trinuclear gold clusters functionalized with N-heterocyclic carbene (NHC) ligands were thermally decomposed to form NHC-stabilized gold nanoparticles. By systematically adjusting the substituents and electronic structures of the N-heterocyclic carbenes, the size and Au active sites of the resulting gold nanoparticles were controlled, thereby modulating their catalytic performance in the conversion of CO to CO2 at the minimum temperature of 50 °C with an excellent efficiency.
