Barium hexaaluminate as a novel promising support for ruthenium-based ammonia synthesis catalysts
High-surface area (49 m(2)/g) barium hexaaluminate (BHA) has been successfully synthesized by reverse microemulsion method. The BHA supported Ru catalyst showed significantly higher activity and structural stability than Ba-promoted Ru catalyst supported on MgO under ammonia synthesis conditions.
