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 nanometer particles, in particular to a method for synthesizing nanometer particles through chemical reaction by spray mixing. 【Background technique】 [0002] Due to the unique electrical, optical, and mechanical properties of small-sized and microstructured nanoparticles, a lot of research has been devoted to the synthesis of nanoparticles. The existing nanoparticle synthesis methods include the following: vacuum deposition method, sol-gel method, chemical precipitation method and spray pyrolysis method. Among the above nanoparticle synthesis methods, methods such as vacuum deposition, sol-gel method, and spray pyrolysis generally require more 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 so on. [0003] In the...
