摘要

用n -杂环碳烯（NHC）配体功能化的三核金团簇进行热分解，形成NHC稳定的金纳米颗粒。通过系统地调整n -杂环碳烯的取代基和电子结构，可以控制金纳米颗粒的大小和Auδ活性位点，从而调节其在最低温度50℃下催化CO转化为CO2的效率。

NHC-ligated gold nanoparticles derived from cluster precursors for carbon monoxide oxidation reactions†

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^δ− 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.
