Publication date: Available online 16 November 2019Source: Materials Today: ProceedingsAuthor(s): K. Sowri Babu, V. Himamaheswara Rao, D. Demudu BabuAbstractThe preparation of ZnO-graphite nanocomposite in a novel route by two step process is reported in this paper. In the first step, ZnO nanoparticle solution is prepared by sol-gel method. In the next step, certain quantity of as prepared ZnO nanoparticle gel is added to the graphite powder and grinded for sufficient time to drive the ZnO nanoparticles into the pores of graphite. The powder prepared by the above process was annealed at different temperatures from 500 °C to 800 °C to obtain ZnO-graphite nanocomposite. Scanning Electron Microscope (SEM) pictures showed ZnO nanoparticles of uniform size (≈20 nm) distributed in the graphite matrix. This nanocomposite is further characterized by using X-Ray diffraction and Raman spectroscopy and the results were discussed in detail.
