MULTI-WALLED carbon nanotubes decorated Zinc oxide ..........(MWCNTs/ZnO) nanocomposites with ratio of (99: 1 wt %) was prepared using sol gel method. Transmission Electron Microscope (TEM) and The X-ray diffraction pattern (XRD) showed that the MWCNTs/ZnO nanocomposites was synthesized with particle size ranging from 2-7 nm and crystalline size about 7nm. The Field Emission Scanning Electron Microscopy (FESEM) images demonstrate that ZnO had grown on the walls of MWCNTs were uniformed layer in the shape of thin film layer of nanospheres covering the surface of the tubes, also the energy dispersive X-ray spectrum (EDX) and Fourier Transformed Infrared spectroscopy (FTIR) prove the presence of ZnO without any impurities
