| Abstract: | Zn-Cu alloy nanocomposites were prepared directly from Zn-Cu alloy wire (w(Zn)=0.65)) by wire electrical explosion (WEE) method. The average particle size was in the range of 60-90 nm. Subsequently, Zn-Cu nanoparticles were oxidized to form ZnO-CuO nanocomposites after calcination at 500 ℃ in air for 2 h. X-ray diffraction (XRD) and scanning electron microscopy (SEM) were employed to analyze the structure and morphology of the ZnO-CuO nanocomposites. Furthermore, the ZnO-CuO nanocomposites were coated on the surface of a ceramic tube to fabricate thick filmgas sensors, which showed strong gas sensing activities to C2H5OH. |
