摘要:

平均粒径为2-10 nm的聚合物稳定的Au纳米簇(NCs)表现出独特的催化性能.多个研究表明,影响聚合物稳定的Au NCs催化活性的主要因素为:Au NC尺寸的控制、聚合物的选择以及反应条件的优化.这是由于聚合物稳定的Au NCs在多个催化反应中表现出明显的尺寸效应,其催化活性也因所采用的聚合物和反应条件的不同而不同.为了阐明影响聚合物稳定的Au NCs催化活性的内在原因,众多研究者关注于聚合物稳定的Au NCs催化中的理论计算与实验的相互影响.本文主要总结了聚合物稳定的Au NCs中这种相互影响的研究进展.

Abstract:

Polymer-stabilized Au nano clusters (NCs) with mean diameters of 2-10 nm exhibit unique catalytic properties. Several studies have shown that the key factors affecting the catalytic activity of polymer-stabilized Au NCs are control of the Au NC size, appropriate selection of polymers and optimization of the reaction conditions. This is because polymer-stabilized Au NCs exhibit a clear size effect in several catalytic reactions, and the catalytic activity differs with the type of polymer used and the reaction conditions. In order to elucidate the reason underlying the catalytic activity of the polymer-stabilized Au NCs, much attention is being devoted to the interplay of theoretical calculations and experiments in catalysis by polymer stabilized Au NCs. The present article mainly summarizes our progress in understanding this interplay in polymer-stabilized Au NC catalysis.
