Abstract
A(2)BO(4) type oxides consisting of an alkali earth metal and tin show ed high selectivity (> 99%) and activity for the oxidative coupling of methane at 1023 K in a methane-water redox system where active oxygen species ware regenerated by water. The products were C-2 hydrocarbons and hydrogen. Repeated reaction-oxidation cycles showed that the oxid e is stable under both oxidative and reductive atmosphere. Doping of B i to the oxide was found to enhance the activity for the oxidative cou pling of methane.
