Abstract
The present invention relates to a nano-metal particles and a preparation process thereof. Specifically, the nano-metal particles are prepared by a process comprising the steps of: a) providing a solution of a metal precursor; b) providing a mother liquor comprising a reducing agent; c) atomizing the solution of the metal precursor; and d) allowing the metal precursor to react with a reducing agent to form the nano-metal particles, wherein the metal precursor has a higher solubility in the first solvent than in the mother liquor. The present process for preparing nano-metal particles not only has the advantages of the traditional liquid phase chemical reduction process such as simple equipment, easy availability of raw materials, low cost, easy control of conditions, high yield, large output and the like, but also may produce the nano-metal particles having a very desirable particle size and particle size distribution.
