Příprava a charakterizace kompozitních nanočástic core-shell metodou binární disperze

Abstract

This work is about preparation of composite core-shell nanoparticles using new binary aerosol dispersion method. In theoretical part there are discussed basics of semiconductors, photocatalytic processes, summary of known methods of preparation of nanoparticles and influence of different parameters on photocatalytic efficiency of semiconductor nanoparticles. Further there is described binary aerosol dispersion method used for preparation of core-shell nanostructures SiO2-ZnS, characterization of prepared nanoparticles using DLS, TEM and UV-VIS spectral photometry methods and measurement of photocatalytic efficiency by degradation of methylen blue.
