Abstract:
One of the considerable issues in fullereneresearch is low yield of endohedral fullerene production.In this project, synthesis and optimization of endohedral metallofullereneproduction was undertaken byarc reactor applying vertical graphite electrodes, using vaporizing composite lanthanum-oxide-graphite-dopped rod. Increasing the efficiency of endohedral fullerrene production in sootwas followed applyingcarbide formation in electrode which was studied by X-ray diffraction(XRD), thermogravimetric analysis(TGA) and infrared (IR) spectroscopy. In addition, as a simple and fast method, the liquid column chromatography was applied in separation and purification of fullerenes as well as endohedral fullerene. Futhermore, after extraction of the fullerenic contents from precusuor soot using n-hexane and dimethylformamide as eluent solvents, characterization of endohedral fullerene was followed applying UV-visiblespectroscopy and high performance liquid chromatography(HPLC)
