Evaluation of the Structural Deviation of Cu/Cu2O Nanocomposite Using the X-ray Diffraction Analysis Methods

We successfully synthesized Cu/Cu2O nanocomposites using the wet chemical synthesis method. All X-ray diffraction (XRD), Reference Intensity Ratio (RIR), and Rietveld refinement methods confirmed that compounds Cu Cu2O are free of impurities. Scanning Electron Microscope (SEM) Transmission electron microscopy (TEM) images show morphology interactions in structure. The formation mechanism is also explained by five stages: precursor, nucleation, growth, aging, reduction. changes crystallization parameters under variations reaction temperature (Tv) stirring speed (Sv) were agreement with XRD database. lattice constant crystal nanocomposite increases rising reaction, leading to unit cell expansion, while increasing stirring—rate leads a random size distribution parameter. Due imperfect growth crystal, induced crystallite was calculated Williamson-Hall model, precise parameter values Nelson-Riley function.
