Synthesis of Zinc Oxide Nanoparticles Coated with Silicon Oxide

The new technique of synthesis of zinc oxide nanoparticles for biomedical applications is reported. As a precursor, the metal-organic framework ZIF-8 was used, on the basis of which zinc oxide nanoparticles of size 20‒30 nm were obtained. Moreover, a porous ZIF-8 structure was used for the introduction of a silicon source. As a result, after thermal decomposition, zinc oxide nanoparticles with 5‒6 nm size coated by the SiO2 layer were obtained. Synthesized materials were comprehensively characterized.
