- Аннотация: One-pot synthesis of colloidal Au/ZnO and Ag/ZnO nanohybrid structures was carriedout. The copolymers of maleic acid—poly(N-vinyl-2-pyrrolidone-alt-maleic acid), poly(ethylene-altmaleicacid), or poly(styrene-alt-maleic acid) were used as templates for the sorption of cations ofmetals-precursors and stabilization of the resulting nanoheterostructures. Simultaneous productionof two types of nanoparticles has been implemented under mild conditions in an aqueous alkalinemedium and without additional reagents. Equimolar ratios of the metal cations and appropriateload on all copolymers were used: molar ratio of maleic acid monomeric units of copolymer/gold(silver)cations/zinc cations was 1/0.15/0.23 (1/0.3/0.15). The process of obtaining the heterostructureswas studied using UV-Vis spectroscopy. The kinetics of the formation of heterostructureswas influenced by the nature of the maleic acid copolymer and noble metal cations used. A highreaction rate was observed in the case of using zinc and gold cations-precursors and a copolymer ofmaleic acid with N-vinylpyrrolidone as a stabilizer of nanoparticles. The structure of the synthesizedpolymer-stabilized heterostructures was studied using instrumental methods of analysis—XPS, FTIR,PXRD, and TEM. Under the conditions used, stable colloidal solutions of heterodimers were obtained,and such structure can be converted to a solid state and back without loss of properties.
