摘要
Ammonia is a promising carrier for energy storage due to its high hydrogen content, low storage and transportation costs, and zero carbon emissions. Plasma catalysis shows excellent potential for sustainable ammonia synthesis; however, searching for suitable catalysts is ongoing. La(OH)3 was studied due to its rich basic sites and oxygen vacancies, which are beneficial for plasma-catalyzed ammonia synthesis. The optimal reaction conditions were investigated, and a maximum ammonia synthesis rate of 37.13 μmol/(min•g-cat) was achieved. H2 plasma treatment enhanced the catalytic activity of La(OH)3, and ammonia synthesis rate of 40.00 μmol/(min•g-cat) were achieved. This study contributes to the development of efficient catalysts for plasma-catalyzed ammonia synthesis and highlights the potential of La(OH)3 as a promising catalyst.
