Preparation of Composite of ZnS Nanoparticles and Montmorillonite by Cavitation Deposition

Popis výsledku v původním jazyce

Physics and chemistry of very small particles emanate from a long-term tradition of colloidal chemistry. An important area of contemporary nanotechnologies is preparation of nanoparticles with size lower than 100 nm by top-down and bottom-up methods. Bottom-up methods turned out to be more suitable for preparation of nanoparticles than methods based of various chemical reactions. In our previous works we referred about preparation of ZnS nanoparticles with size about 3-5 nm stabilized by cationic surfactants like cetyltrimethylammonium bromide (CTAB) in aqueous dispersions by chemical precipitation of zinc acetate and sodium sulphide. CTAB was found to significantly influence size of ZnS nanoparticles. A basic requirement for their photocatalytic properties is maximal reactive surface area. For practical manipulation these nanoparticles were deposited on caring larger particles which formed dray powders. In this work, a new method for preparation of composite of ZnS nanoparticles and m
