Abstract

Disclosed is a method for synthesizing nanometer particles, which characterized in the steps: providing at least one atomization nozzle and one reaction chamber, which communicate to each other; providing at least two reactants, at least one of which is liquid phase reactant; atomizing the liquid phase reactant by the atomization nozzle and jetting to the reaction chamber; mixing at least two reactants and depositing particles of nanometer structure.

Description

【Technical Field】 [0001] The invention relates to a method for synthesizing nano particles, in particular to a method for synthesizing nano particles by spray mixing and chemical reaction. 【Background technique】 [0002] Due to the unique electrical, optical and mechanical properties of small-sized microstructured nanoparticles, a lot of research has been devoted to the synthesis of nanoparticles. The existing methods for synthesizing nanoparticles are as follows: vacuum deposition method, sol-gel method, chemical precipitation method and spray pyrolysis method. Among the above-mentioned synthesis methods of nanoparticles, the vacuum deposition method, sol-gel method and spray pyrolysis method generally require relatively expensive equipment, and the process is complicated, which is not conducive to the mass production of nanoparticles. The chemical precipitation method has relatively simple equipment. , Low cost, suitable for large-scale production and other advantages. [0003]...
