One Pot Synthesis, Surface and Magnetic Properties of Cu2O/Cu and Cu2O/CuO Nanocomposites

A series of copper-based systems containing two different nanocomposites (Cu2O/CuO and Cu2O/Cu) was synthesized by the egg white assisted auto-combustion route. This method distinguished simplicity its steps, low cost, one-pot synthesis process at temperature and, short time. The characterization as prepared carried out using X-ray diffraction (XRD), Fourier-transform infrared (FTIR), Scanning electron microscope (SEM) transmission micrograph (TEM), Energy dispersive spectrometry (EDS) techniques. Surface magnetic properties obtained were determined N2 adsorption/desorption isotherms 77 K vibrating sample magnetometer (VSM) technique. XRD results confirmed formation Cu2O/CuO Cu2O/Cu with ratios well crystalline CuO, Cu2O, Cu phases. FTIR combusted product displays presence both CuO respectively. SEM/EDS TEM confirm a porous nanocomposite Cu, O, C elements. change in concentration oxygen vacancies surface or interface nanoparticles resulted changes their magnetization. Based on this study, it is possible to obtain nanocomposite-based copper multiple valances simple inexpensive route which can be suitable for fabrication transition metal composites.
