An evidence of active surface $ MoO_{x} $ over $ MgMoO_{4} $ for the catalytic oxidative dehydrogenation of propane
Abstract In order to clarify whether $ MgMo_{x} $$ O_{y} $ catalysts with slight excess of molybdenum relative to the stoichiometric $ MgMoO_{4} $ compound showed increased activities for propene formation in the propane oxidative dehydrogenation, we investigated the catalytic properties of $ MoO_{3...

| 520 | |a Abstract In order to clarify whether $ MgMo_{x} $$ O_{y} $ catalysts with slight excess of molybdenum relative to the stoichiometric $ MgMoO_{4} $ compound showed increased activities for propene formation in the propane oxidative dehydrogenation, we investigated the catalytic properties of $ MoO_{3} $ supported on $ MgMoO_{4} $ and of $ MgMo_{x} $$ O_{y} $ catalysts treated with acid or base. Supporting $ MoO_{3} $ on magnesium-rich $ MgMo_{0.99} $$ O_{y} $ catalysts which are poorly active, or treating them with acetic acid to remove excess magnesium, resulted in drastic activity increases. On the other hand, the ammonia treatment of molybdenum-rich $ MgMo_{1.05} $$ O_{y} $ catalysts which are highly active turned out to give a remarkable decrease in activity, because surface $ MoO_{x} $ dissolved in ammonia water. A clear correlation was observed between the catalytic activities for propane oxidation and the dehydration of 2-propanol to propene over the supported catalyst and the treated catalysts. Since the bulk structures were unchanged by supporting or by the treatments, the existence of $ MoO_{x} $ clusters formed on the surface of $ MgMoO_{4} $ are responsible for the activities in the oxidative dehydrogenation of propane. | ||

An evidence of active surface $ MoO_{x} $ over $ MgMoO_{4} $ for the catalytic oxidative dehydrogenation of propane |
| abstract |
Abstract In order to clarify whether $ MgMo_{x} $$ O_{y} $ catalysts with slight excess of molybdenum relative to the stoichiometric $ MgMoO_{4} $ compound showed increased activities for propene formation in the propane oxidative dehydrogenation, we investigated the catalytic properties of $ MoO_{3} $ supported on $ MgMoO_{4} $ and of $ MgMo_{x} $$ O_{y} $ catalysts treated with acid or base. Supporting $ MoO_{3} $ on magnesium-rich $ MgMo_{0.99} $$ O_{y} $ catalysts which are poorly active, or treating them with acetic acid to remove excess magnesium, resulted in drastic activity increases. On the other hand, the ammonia treatment of molybdenum-rich $ MgMo_{1.05} $$ O_{y} $ catalysts which are highly active turned out to give a remarkable decrease in activity, because surface $ MoO_{x} $ dissolved in ammonia water. A clear correlation was observed between the catalytic activities for propane oxidation and the dehydration of 2-propanol to propene over the supported catalyst and the treated catalysts. Since the bulk structures were unchanged by supporting or by the treatments, the existence of $ MoO_{x} $ clusters formed on the surface of $ MgMoO_{4} $ are responsible for the activities in the oxidative dehydrogenation of propane. © Kluwer Academic Publishers 1997 |
