The results of studies of the partial oxidation of methane with a number of silica-supported heteropoly oxometalates have been reported. Within the range of experimental conditions used, it has been found that molybdenum-containing heteropoly acids are active and selective catalysts for the partial oxidation of methane, with activities greater than those of the molybdena/silica catalysts but less than those of vanadium pentoxide/silica. Selectivities are rather similar in all cases. In contrast, tungsten-based heteropoly acids showed little or no activity in the partial oxidation of methane. As a consequence of the importance in the partial oxidation of methane of supporting of the 12-molybdophosphoric acid (HPMo), the earlier work has been extended to examine various aspects of these supported catalysts, particularly the nature and stability of the supported species.
