Abstract
Provided is a method of making colloidal metal nanoparticles. The method includes the steps of: mixing a metal aqueous solution and a reducing agent to form a mixture solution in a reaction tank; heating the mixture solution and undergoing a reduction reaction to produce a composition containing metal nanoparticles, residues and gas, wherein the amount of the residues is less than 20% by volume of the mixture solution, and guiding the gas out of the reaction tank; dispersing the metal nanoparticles with a medium to obtain colloidal metal nanoparticles. By separating the reduction reaction step and the dispersion step, the method of making colloidal metal nanoparticles is simple, safe, time-effective, cost-effective, and has the advantage of high yield.
