Abstract
The influence of “superacidic” modification has been shown to enhance the methane combustion activity of ZrO2 at 800 °C. Modification with SO4 2−, Fe/Mn/SO4 2− and MoO3 has been investigated, with the latter showing the most marked effect although this is a critical function of loading. Ceria–zirconia catalysts are also active, although the compositions studied are not as effective as 5 wt% MoO3/ZrO2 which shows a greater mass normalised activity than Fe2O3.
