Abstract

Ammonia decomposition plays a crucial role in various industrial and environmental processes, including the production of hydrogen, clean energy storage. Plasma catalysis presents a promising option that utilizes the unique properties of plasma to drive chemical reactions at a lower temperature than traditional methods. This study examines the effectiveness of plasma catalysis for ammonia decomposition on ruthenium (Ru) supported on alumina (Al₂O₃) as the catalyst. The research indicates that the catalytic performance of Ru is significantly impacted by its loading on the alumina support. The study identifies optimal Ru loading conditions, which lead to substantial improvements in ammonia decomposition. The incorporation of alkali metal promoters, such as sodium (Na), potassium (K), lithium (Li), and cesium (Cs), enhances the catalytic activity, especially at lower Ru loadings (0.01%). This study highlights the potential of Ru-based catalysts with alkali metal promoters in plasma catalytic systems for efficient ammonia decomposition.
