At dehydrogenation temperatures (300} been reported. At dehydrogenation temperatures (300}6003C), oxygen can react with hydrogen to In contrast, the dehydrogenation reaction is endothermic. Thus, thermal matching of the heat released consumed by the dehydrogenation reaction would allow for an isothermal system. Because the hydrogenation
