COLONIA, Roberto; MARTINEZ, Vanessa C.; SOLIS, José L.  e  GOMEZ, Mónica M.. Nanoparticle synthesis of zinc peroxide: structural and morphological characterization for bactericidal applications. Rev. Soc. Quím. Perú [online]. 2013, vol.79, n.2, pp.126-135. ISSN 1810-634X.

Zinc peroxide (ZnO₂) nanoparticles were synthesized by sol-gel technique. The chemicals used for the synthesis were zinc acetate di-hydrate (Zn(CH₃COO)₂.2H₂O) and hydrogen peroxide (H₂O₂) at 30% in an aqueous solution with sonication. The structure of the ZnO₂ nanoparticles was characterized by X-ray diffraction. While the morphology and the cluster size were determined using scanning and transmission electron microscopy. For a preliminary evaluation of the bactericidal properties of the ZnO₂, the material was exposed to Staphylococcus aureus, Escherichia coli y Bacillus subtili, and the nanoparticles presented good bactericidal properties.

Palavras-chave : zinc peroxide; nanoparticles; bactericidal; sonication.
