摘要

Hydrogen is a sustainable, renewable, and high-energy-density carrier, playing a crucial role in advancing the low-carbon economy. Ammonia borane (AB) emerges as a promising candidate material for H2 storage due to its high hydrogen capacity, environmental friendliness, and excellent stability. Nevertheless, the stability of AB in aqueous solution requires the use of a catalyst to facilitate hydrolysis for hydrogen generation. Cu, a base metal, exhibits significant reactivity in AB hydrolysis (ABH) and is both earth-abundant and cost-effective. This review comprehensively summarizes recent advancements in Cu-based nanomaterials employed as catalysts for ABH. Initially, the focus is on Cu-based mono-, bimetallic, trimetallic, compounds, and their composites, utilized in catalytic ABH for H2 production. Subsequently, the review explores photo-enhanced ABH for H2 generation and the in situ applications of this reaction.
