Mn-doped TiO2 Nanowires Catalysts for the Oxidative Coupling of Methane |
| 초록 |
The direct conversion of methane to hydrocarbons with higher carbon numbers has been studied and the oxidative coupling of methane (OCM) is a promising example of the direct conversion methods. The OCM is an ideal method to produce C2 hydrocarbons, including ethane and ethylene. In this study, the OCM using the Mn-doped TiO2 nanowire catalysts was performed, which was selected for the OCM because of high preparation temperature that can secure the stability of the nanowire catalysts during the OCM reaction (700 - 850 oC) and because the transition metal doping to TiO2 nanowire may adjust the catalytic activity of TiO2. A 2wt% Mn-doped TiO2 nanowire catalyst exhibited the highest conversion and C2 yield because of its moderate oxidation activity. It was also observed that the wire/rod-shaped nanostructures exhibited the best catalytic properties. |
