| Abstract: | 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 ((hbox {C}_{60})) was investigated and then activation of surface of (hbox {Sn-C}_{60}) via (hbox {O}_{2}) molecule was examined. In second step, the SiO oxidation on surface of (hbox {Sn-C}_{60}) via Langmuir Hinshelwood (LH) and Eley Rideal (ER) mechanisms was investigated. Results show that (hbox {O}_{2}hbox {-Sn-C}_{60}) can oxidize the SiO molecule via (hbox {Sn-C}_{60}hbox {-O-O}^{*} + hbox {SiO}rightarrow hbox {Sn-C}_{60}hbox {-O-O}^{*}hbox {-SiO} rightarrow hbox {Sn-C}_{60}hbox {-O}^{*} + hbox {SiO}_{2}) and (hbox {Sn-C}_{60}hbox {-O}^{*} + hbox {SiO}rightarrow hbox {Sn-C}_{60} + hbox {SiO}_{2}) reactions. Results show that SiO oxidation via the LH mechanism has lower energy barrier than ER mechanism. Finally, (hbox {Sn-C}_{60}) is an acceptable catalyst with high performance for SiO oxidation in normal temperature. |
