Abstarct: Fullerenes are cage-like molecules that are formed by heating graphite and has cut icosahedral geometry form. Fullerene has been considered by researchers due to unique structure and optical, mechanical properties, biocompatibility, drug delivery and other abundant properties. In this regard, many studies have been conducted on functionalizing and connection of Fullerene to polymers and different molecules for increasing solubility and improving its properties and have provided structure of new nanocomposites in different fields. Spinel structure materials have attracted many people due to their thermal stability, magnetic, electronic and optical properties. Among these materials, zinc aluminate (Gahnite) has drawn considerable attention as a catalytic material with desirable properties such as high thermal stability, high mechanical resistance, low temperature sinterability, better diffusion and ductility, low surface acidity and hydrophobicity. Due to these properties, it was used as a high temperature material, catalyst, catalyst support and optical coating. For this reason, production of nanocomposite and use of Fullerene in the composite can be accompanied by many applications. In this research, zinc aluminate nanoparticles with formula of ZnAl2O4 and then C60-ZnAl2O4 nanocomposite with hydrothermal method were prepared and effect of baking temperature on Structure and properties of the samples was studied. The samples were characterized by Xray diffraction (XRD), infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and ultraviolet visible (UV-VIS) spectroscopy. The sample size was obtained by using XRD data. The sample structure was confirmed by spectrum FT-IR. TEM pictures of sample showed that nanocomposites are made in the context of fullerenes and its size corresponds to the size obtained from XRD. SEM pictures showed that the particles are ideal and spherical in shape.
