One-dimentional nanostructures in the form of nanorods, nanowires, nanofibers or nanotubes, appear as an exciting research area for their great potential of applications. Zinc oxide is an n-type semiconductor that has been well known for its applications in pigments, rubber additives, gas sensors, solar cells, varistors, and optical devices. In this aspect, many of the previous investigations on pure and doped zinc oxide prepared by different methods like precipitation, hydrothermal, microemulsion, ultrasonic, sol–gel, solid-state reaction. In this study, we report the synthesis of copper oxide decorated zinc oxide nanorods by microemulsion and solvothermal method. Scanning electron microscopy (SEM), energy-dispersive X-ray (EDX) spectroscopy, X-ray diffraction (XRD), Fourier transform infrared spectrum (FT-IR) and X-ray photoelectron spectroscopy (XPS) were used to characterize the as-synthesized copper oxide decorated zinc oxide nanorods. Zinc oxide nanorods were synthesized by microemulson method. 2, 9, 16, 23-tetranitrophthalocyanine copper (II) (TNCuPc)/zinc oxide nanorod structures were synthesized by solvothermal method. After calcination of TNCuPc/zinc oxide nanorod structures, copper oxide decorated zinc oxide nanorods were successfully synthesized. The results showed that the copper oxide were successfully grown on the zinc oxide nanorods substrates.
