The paper presents a method for obtaining nanoparticles of ZnO by thermal decomposition of the Zn-containing compounds. The experiment was based on the thermal decomposition of basic zinc carbonate to zinc oxide (with a content of 58-61 wt.%). Basic zinc carbonate was analysed by derivatography and then annealed at a selected temperature (about 600ºC) for about 1 h. Products of thermal decomposition of the compound were studied by XRD analysis and SEM scanning microscopy.

Zno Powder

The ZnO powder was successfully obtained by calcining the basic zinc carbonate, which was synthesized from clinker digestion solution of zinc oxide ore using analytical Na2CO3. The factors of mol ratio of Na2CO3to ZnSO4and reaction temperature were discussed at stirring intensity 400 rpm. Both the obtained basic zinc carbonate and ZnO powders were characterized using XRD, EDS and SEM. The thermal decomposition of basic zinc carbonate was also investigated below 600°C. The results show that the ZnO powder was wurzite hexagonal structure and the well-crystallized ZnO powder was uniformly spherical particles and distributed in a narrow range.

Zinc oxide (ZnO) nanoparticles were obtained by thermal decomposition of one-dimensional zinc?benzenepolycarboxylato complexes as single- -source precursors at 450 ?C in an air atmosphere. The mechanism and kinetics of thermal degradation of zinc?benzenepolycarboxylato complexes were analyzed under non-isothermal conditions in an air atmosphere. The results of X-ray powder diffraction and field emission scanning electron microscopy revealed hexagonal wurtzite structure of ZnO with an average crystallite size in the range of 39?47 nm and similar morphology. The band gap and the specific surface area of ZnO nanoparticles were determined using UV?Vis diffuse reflectance spectroscopy and the Brunauer, Emmett and Teller method, respectively. The photoluminescent, photocatalytic and antimicrobial properties of the ZnO nanoparticles were also examined. The best photocatalytic activity in the degradation of C. I. Reactive Orange 16 dye was observed for the ZnO powder where the crystallites form the smallest agglomerates. All ZnO nanoparticles showed excellent inhibitory effect against Gram-positive bacterium Staphylococcus aureus and Gram-negative bacterium Escherichia coli.

The absorption of carbon dioxide and water vapour by zinc oxide to form basic zinc carbonate was studied for a range of gas pressures and reaction temperatures. Water pretreatment of the oxide was found to influence the initial stages of the reaction. The CO2- and water-contents of the products varied according to the reacting conditions but in all cases a highly-disordered basic zinc carbonate was formed which showed an increase in order on ageing.
