Barium Hexaaluminate as a Novel Promising Support for Ruthenium-based Ammonia Synthesis Catalysts

High-surface area (49 m2/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.
