|Title:||METHOD FOR PREPARING PRECIOUS METAL ISOLATED ATOMS IN SOLUTION, AND APPLICATIONS THEREOF|
A method for preparing precious metal isolated atoms in a solution, and applications thereof. The method comprises: fully mixing a protective agent, a precious metal compound, a reducing agent and a solvent, and carrying out a reaction in a temperature to obtain precious metal isolated atoms, so as to obtain the precious metal isolated atoms capable of stably existing in a solution. The solution containing the precious metal isolated atoms is loaded to a solid medium by means of a dipping method, so that a new material comprising the precious metal isolated atoms and the solid medium can be formed. Alloy materials, catalysts and the like can be prepared by using a single-atom solution. Reduced-state single atoms in a solution phase are prepared. Compared with the synthesis of a metal material in a solution phase in the conventional art, generation of metal nano particles is avoided, and a reduced-state single-atom solution existing in the form of single metal atoms is obtained. Compared with a single-atom material loaded to the surface of a solid, the precious metal in the present invention has the characteristics of a great loading capacity and high stability.
