METHOD OF AEROSOL SYNTHESIS OF CORE-SHELL NANOPARTICLES AND REFINE CONDITIONS OF ITS APPLICABILITY
Original language description
In this work we generalized and specified aerosol synthesis method of core-shell nanoparticles. This synthesis method was used with success in our previous publication about preparation of photocatalytic core-shell SiZnS nanoparticles. Reaction of two precursors takes place on the surface of carrier nanoparticles and leads to formation of photoactive shell. Likewise, in other microemulsion methods, desired thickness of shell is achieved by limiting the extent of reaction. Unlike to the conventional microemulsion methods, both precursors are dissolved in a same solvent. In our method of application aerosol synthesis, the carrier particles are dispersed in aqueous solution of the first precursor with a suitable concentration. This dispersion, which contains dispersed particles, is converted into a form of aerosol microdroplets in ultrasonic nebulizer. After that the aerosol is injected by air flow on the surface of a vigorously stirred solution containing the second precursor, which is in excess. The reaction near surface of carrier particles is largely heterogeneous and the shell growth is limited by an amount of the first precursor located in the aerosol droplet. Desired coating thickness is achieved by setting the initial parameters such as size and concentration of carrier nanoparticles and concentration of the first precursor. This work follows our previous publication, generalizes aerosol synthesis technology of core-shell nanostructures and discusses its prediction formulas accuracy.
