Abstract

Abstract: The Ru/Ba-MgO catalyst for ammonia synthesis was prepared by ultrasound electrostatic adsorption. Ba was adsorbed on the surface of Mg(OH)2 through its electrostatic force, which improved the properties of the Ba-MgO support.

Key words: barium, nano-magnesia, ultrasound coating, ultrasound electrostatic adsorption, ruthenium-based catalyst, ammonia synthesis
