      In recent years, the discovery of metal catalysts for the oxidation of silicon monoxide (SiO) has become extremely important. In first step, the Sn adoption of fullerene (C$_{60}$) was investigated and then activation of surface ofSn-C$_{60}$ via O$_2$ molecule was examined. In second step, the SiO oxidation on surface of Sn-C$_{60}$ via Langmuir Hinshelwood (LH) and Eley Rideal (ER) mechanisms was investigated. Results show that O$_2$-Sn-C$_{60}$ can oxidize the SiO molecule via Sn-C$_{60}$-O-O$^∗$ $+$ SiO $\to$ Sn-C$_{60}$-O-O$^∗$-SiO $\to$ Sn-C$_{60}$-O$^∗$ $+$ SiO$_2$ and Sn-C$_{60}$-O$^∗$ $+$ SiO $\to$ Sn-C$_{60}$ $+$ SiO$_2$ reactions.Results show that SiO oxidation via the LH mechanism has lower energy barrier than ER mechanism. Finally, Sn-C$_{60}$ is an acceptable catalyst with high performance for SiO oxidation in normal temperature.
