Abstract

Metal and metal oxide nanopowders synthesized via cryochemical technologies are distinguished by their absence of toxic reagents, solvents, and stabilizers, rendering them well-suited for biomedical applications. In this article, the cryochemical approach—cryogenic precipitation of silver and zinc as carbonates and their subsequent thermal decomposition—is used to produce highly dispersed silver and zinc oxide powders. The size of the obtained nanoparticles is 1–7 nm for silver and 7–17 nm for zinc oxide. Obtained nanoparticles and their precursors were characterized by X-ray diffraction, FTIR-, UV-spectroscopy, and TEM methods.
