ZnO2 nanoparticles show promise in various fields such as optoelectronics, photocatalysis, sensorics, biomedicine, and theranostics due to their semiconducting and oxidizing properties. The synthesis of ZnO2 NPs using lipophilic surfactants has been explored and proven to be feasible. The dispersed system type and surfactant nature do not significantly impact the size of the NPs, and films made from ZnO2 and Au NPs exhibit different morphologies.
ZnO2 nanoparticles (NPs) have been studied, which, due to their semiconducting and oxidizing properties, are promising for the development of new materials for optoelectronics, photocatalysis, sensorics, biomedicine, and theranostics. The synthesis of ZnO2 NPs in dispersed systems based on lipophilic surfactants has been tested. The possibility of simple synthesis of ZnO2 NPs similar to 5 nm in size by the reaction of Zn (CH3COO)(2) and H2O2 in reverse micelles and emulsions of surfactants Brij 30, Span 80, and AOT has been shown. It has been found that the type of dispersed system and the nature of surfactants of the studied series have no strong effect on the size of NPs. The powder of ZnO2 NPs exhibits photoluminescence with an emission maximum at 520 nm; upon heating, it decomposes to ZnO with the release of oxygen and an exotherm with a maximum at 213 degrees C. Using organosols of ZnO2 NPs and their mixtures with Au NPs, films were obtained on glass and polyethylene terephthalate substrates, as well as ZnO films by heating the ZnO2 films. The ZnO2 and ZnO films have a granular morphology, the composite ZnO2 and Au films have an island morphology based on spheroidal agglomerates of Au NPs with inclusions of ZnO2 nanocrystals.
