Title:
NANO METAL PARTICLE AND PREPARATION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2017/005132
Kind Code:
A1
Abstract:
A preparation method of a nano metal particle comprises the following steps: a) providing a metal precursor solution; b) providing a mother liquor containing a reducing agent; c) atomizing the metal precursor solution and causing the atomized metal precursor solution to contact with the mother liquor; and d) allowing a metal precursor to react with the reducing agent so as to form a nano metal particle, wherein the metal precursor has a higher solubility in a first solvent than in the mother liquor. Further provided is a nano metal particle. The above method has the advantages of a traditional liquid-phase chemical reduction, needs simple equipment to produce the nano metal particle, and has a low cost, easily controlled conditions, a high production yield and a high productivity. Moreover, the resulting nano metal particle has a desired particle diameter and particle size distribution.
