Zinc peroxide nanoparticles (ZnO2 NPs) were prepared by reacting zinc(II) isobutylcarbamate, as an organometallic precursor, with hydrogen peroxide (H2O2) at 60 °C. Polyethylene glycol and polyvinylpyrrolidone were used as stabilizers, which suppressed aggregation of the ZnO2 NPs. Conditions such as concentrations of H2O2 and the stabilizer were systemically controlled to determine their effect on the formation of nano-sized ZnO2 NPs. The formation of stable ZnO2 NPs was confirmed by UV-vis, Raman spectroscopy, X-ray photoelectron spectroscopy, transmission electron microscopy (TEM), scanning electron microscopy (SEM), and X-ray diffraction. The TEM images revealed that polyvinylpyrrolidone-stabilized ZnO2 NPs (diameter, 10–30 nm) were well dispersed in the organic solvent. Quite pure ZnO NPs were obtained from the peroxide powder by simple heat treatment of ZnO2. The transition temperature of 170 oC was determined by differential scanning calorimetry.
