Preparation method of monometallic or bimetallic nanoparticle-supported catalyst

A preparation method of a monometallic or bimetallic nanoparticle-supported catalyst is disclosed. The synthesis of metal nanoparticles with different shapes, sizes, and atomic structures is affected by nucleation and growth rates. By changing a ratio of strong and weak reducing agents, a suitable double reducing agent is provided for metal nanoparticles with different reduction potentials, where the strong reducing agent is used for rapid nucleation and the weak reducing agent is used for the growth of metal nanoparticles. Accordingly, modulation and control of the nucleation and growth rates can be realized during the synthesis of nanoparticles. In addition, through multiple actions of a combination of reducing agents with different reduction intensities, monometallic/bimetallic nanoparticles of different sizes, shapes, and atomic structures are controllably prepared, which are then supported with a carrier to obtain the monometallic or bimetallic nanoparticle-supported catalyst.
