Abstract

Metal hydrides are promising catalysts in hydrogen-involving reactions. However, downsizing and loading metal hydrides is difficult due to their sensitivity towards oxygen and water. Here, a simple one-pot molten salt synthetical method is proposed to synthesize porous La(OH)₃-supported LaNi₅. The as-synthesized catalyst shows an evident improvement in catalyzing reversible hydrogen storage in liquid organic hydrogen carrier N-ethylcarbazole.
