Impact of n-heptane as surfactant in the formation of CdO nanowires through microwave combustion

Abstract A microwave-assisted combustion route for the preparation of cadmium oxide (CdO) nanowire is carried and its characterization results are discussed. This method resembles a supportive way in the formation of CdO nanowire which is confirmed with the structure and morphological analysis carried for the prepared sample. Microwave combustion method is a cost effective and less time consumption to achieve CdO nanowires. The controlled shapes and size are attained due to microwave irradiation. Yielded sample is investigated with Fourier transformation infra-red (FTIR) spectra, X-ray diffraction (XRD) pattern, energy dispersive X-ray (EDX) spectra and transmission electron microscopy (TEM) with SAED pattern. The formation of CdO phase with a face centered cubic structure is confirmed from XRD spectra and the presence of Cd O metallic bond is also confirmed with FTIR spectra. The formation of CdO nanowires is visualized through the TEM images and presence of elements is also recorded from EDX spectra.
