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.

A salt bath for glass reinforcement, including a nitrate and a metal compound. The mass fraction of the nitrate is not less than 50%, and the nitrate is in a molten state. The metal compound is fused into the nitrate, and the metal compound contains the same metal element as the nitrate. The mass fraction of the metal element in the molecular formula corresponding to the metal compound is greater than the mass fraction in the molecular formula corresponding to the nitrate. Thus, compared with the existing salt bath, under the condition of the same mass, the salt bath can provide more effective amount of metal ions, thereby increasing the strength of glass after reinforcement, and at the same time, the lifetime of the salt bath is increased, reducing the waste of resources and environmental pollution.
