This paper focuses on the catalytic properties of Ag/SnO₂ for low-temperature methane oxidation. The influences of the metal loading (0.2-20 wt.% Ag), support (Al₂O₃, TiO₂, SiO₂) and methane concentration (0.375-1.5%) in the oxidized mixture were investigated. It was observed that the optimal amount of silver in Ag/SnO₂ was 1 wt.%. Lower or higher amounts cause a loss in catalytic activity. SnO₂ was found to be undoubtedly the best support for the title reaction among all tested oxides. A mechanism of methane oxidation over Ag/SnO₂ was proposed.
