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 Auδ− 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.
期刊介绍：
Dalton Transactions is a journal for all areas of inorganic chemistry, which encompasses the organometallic, bioinorganic and materials chemistry of the elements, with applications including synthesis, catalysis, energy conversion/storage, electrical devices and medicine. Dalton Transactions welcomes high-quality, original submissions in all of these areas and more, where the advancement of knowledge in inorganic chemistry is significant.
