Synthesis of uniform MgO/CNT nanorods by precipitation method

In this work, we used carbon nanotubes (CNTs) as a support for synthesis, size control, and morphology of magnesium oxide using the precipitation method. The morphology of MgO nanoparticles varies by changing the weight percent of carbon nanotubes in the solution. Experimental results indicate that, at optimum condition in a mixture of materials, the surface of purified CNTs is covered by MgO nanoparticles completely. The purified CNTs and MgO/CNTs nanorods had average diameters of about 35 and 65 nm, respectively, and their length was in the order of a few micrometers. The structure of CNTs and MgO/CNTs nanopowders has been characterized by analyzing the X-ray diffraction pattern, Fourier transform infrared spectra, and scanning electron microscopy images.
