Title:
METHOD FOR PREPARING SUPPORTED METAL NANO-PARTICLES
Document Type and Number:
WIPO Patent Application WO/2021/083023
Kind Code:
A1
Abstract:
Disclosed is a method for preparing carrier-supported metal nano-particles, the method comprising: dispersing a carrier in pure water, performing an ultrasonic wave treatment to obtain a uniformly dispersed carrier solution, and continuously stirring the carrier solution; formulating a metal salt solution, and dropwise adding the metal salt solution to the carrier solution; freeze-drying the solution to obtain a carrier precursor powder, onto which the metal salt has been uniformly adsorbed; and subjecting the carrier precursor powder to a radiofrequency plasma treatment under vacuum conditions to obtain the supported metal nano-particles.
