Development and biomedical application of nanocomposites: in situ fabrication of ZnO-PbO nanocomposite through microwave method

A novel nanocomposite of ZnO-PbO with flower-like nanostructure was fabricated from zinc acetate and lead nitrate as principle raw materials via an in situ process. The novelty of this study consists in the use of a common approach for fabricating of ZnO and PbO nanoparticles simultaneously. From these experiments the conclusion might be drawn that Zn(NH4)(2)(4+) ions and Pb(OH)(2) act as precursors for the nucleation and growth of ZnO and PbO respectively under microwave irradiation. The precursors formation were carried at two stages: reaction between zinc ions and lead nitrate with ammonium ion and hydroxide sodium respectively. The average crystalline size of Zno and PbO has been analysed by X-ray diffraction (XRD) pattern and estimated to be 43.5 and 54.5 nm for ZnO and PbO respectively. Brunauer-Emmet-Teller (BET-N-2) analyses of as prepared material demonstrated that this nanostructure material has a high specific surface area, as high as 150 m(2) g(-1) which can be promising targets for adsorbent materials. The Formation mechanism of ZnO-Pbo nanocomposite is also studied.
