Title:
MATERIAL COMPRISING REDUCED NOBLE METAL ISOLATED ATOM STABLE IN SOLUTION, AND PREPARATION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/155672
Kind Code:
A1
Abstract:
A material comprising a reduced noble metal isolated atom stable in a solution. The material consists of a reduced noble metal isolated atom and a protective agent. A chain compound containing an ether linkage group is used as the protective agent, so that the reduced noble metal isolated atom stably exists, and the material comprising the noble metal isolated atom is prepared in the solution, and the generation of a nanoparticle caused by the accumulation of a primary isolated atom is avoided in the process of synthesis. The reduced isolated atom of the material is different from a metal nanoparticle, and can be applied to the fields of energy materials, pharmaceutical synthesis, medical materials, catalysts preparation and the like. The present invention provides a basic isolated atom material for synthesis of a controllable number of homogeneous or heterogeneous metal clusters. Also involved is a preparation method for the material comprising the reduced noble metal isolated atom stable in the solution.
