Graphite converted to multi walled carbon nanotubes by a flame deposition method in the atmospheric pressure at 150.C. the process has included Combustion process of graphite in Oxygen/ Nitrogen gases without using catalyst by homemade reactors. The product was assembled on the upper part of the reactor were characterized using Raman spectroscopy, X-ray diffraction, photo- images and scanning electron microscopy SEM. The analysis shows that the combustion process succeeded to separate graphite sheets and forming a mixture of graphite nanotubes with graphene mixture after removing some Vander Walls forces. The work includes supposing mechanism for producing or convert planer graphite to the tubular structure of graphite or multi-walled carbon nanotubes.

Zinc oxide nanoparticles (ZnO NPs) was synthesized via chemical route using sodium hydroxide and zinc chloride (ZnCl2) as a precursor. Zinc oxide nanoparticles/Nanographite-oxide nanocomposite (ZnO/NGO) were synthesized by solution method. The calcination temperature of zinc oxide nanoparticles was 600 °C. The crystal structure of ZnO NPs with average size 32.99 nm was measured by XRD. FT-IR spectrum was used to confirm the presence of functional groups in ZnO and Zn(OH)2 NPs. The dynamic light scattering (DLS) gave a wider nanoparticle size distribution in two peaks with average 725 nm, also the BET and BJH analysis indicated that ZnO NPs / NGO nanocomposite have a well surface area with good nanoparticles diffusion compering as ZnO NPs. The morphology analysis by FESEM technique was given different sizes and shapes nanoparticles (oval, sheet and cubic) with average diameters extended 228.065 and 134.784 nm , 39.63 and 127 nm for Zn(OH)2 and ZnO NPs , NGO sheet and ZnO/NGO nanocomposite respectively.
