摘要
液相化学还原法制备的金属纳米簇具有优良的催化性能,但纳米粒子不稳定,容易团聚。本文对金属纳米簇的多种稳定化研究方法,如采用有机配体稳定、表面活性剂稳定、高分子聚合物稳定、离子液体稳定、生物质稳定等进行了综述,总结了载体对金属纳米簇的分散固定作用,并对如何开展金属纳米簇催化剂的研究提出了一些建议和看法。
Metal nanocluster catalysts prepared by liquid solution chemical reaction usually show excellent catalytic performance. However,the nanoclusters are easily agglomerated,which generally decrease the catalytic performance. Therefore,to stabilize metal nanoclusters against agglomeration is crucial for application. This review summarizes the stabilization methods for metal nanoclusters,such as stabilizations using ligands,surfactants,polymers,ionic liquids or biomasses. The distribution and stabilization effect of support for metal nanoclusters is presented. Furthermore,some opinions about the study of metal nanocluster catalysts are proposed.
