Synthesis and antimicrobial activity of CuO@BaO/CaO nanocomposites using precipitation method

In this study, copper oxide doped barium and calcium oxide were prepared by a simple precipitation method. Using the similar synthetic procedure, to alter the molar radio of metal precursor to prepared four different composites viz., CuO@BaO/CaO (0.5:0.4:0.1), CuO@BaO/CaO (0.5:0.3:0.2), CuO@BaO/CaO (0.5:0.2:0.3) and CuO@BaO/CaO (0.5:0.1:0.4). The prepared composites were evaluating the X-ray diffraction (XRD), Fourier transform infrared spectrum (FT-IR), Scanning Electron Microscopy (SEM) and Energy dispersive X-ray spectroscopy (EDAX) analysis. Antibacterial tests were carried out on the composite produced. The results show that the composite materials exhibit high antibacterial activity with CuO@BaO/CaO(0.5:0.3:0.2) exhibiting stronger activity than CuO@BaO/CaO (0.5:0.4:0.1) because barium concentration decreases and calcium concentration increases.
