Ammonia borane (AB) has been identified as one of the most promising candidates for chemical hydrogen storage. However, the practical application of AB for hydrogen production is hindered by the need of efficient and inexpensive catalysts. For the first time, we report that the incorporation of Mo into [email protected] core-shell structure can significantly improve the catalytic efficiency of hydrogen generation from the hydrolysis of AB. The Cu_0.81@Mo_0.09Co_0.10 core-shell catalyst displays high catalytic activity towards the hydrolysis dehydrogenation of AB with a turnover frequency (TOF) value of 49.6 molH₂ mol_cat⁻¹ min⁻¹, which is higher than most of Cu-based catalysts ever reported, and even comparable to those of noble-metal based catalysts. The excellent catalytic performance is attributed to the multi-elements co-deposition effect and electrons transfer effect of Cu, Mo and Co in the tri-metallic core-shell NPs.

氨硼烷（AB）被确定为化学氢存储的最有希望的候选者之一。然而，由于需要有效和廉价的催化剂，阻碍了AB在制氢中的实际应用。我们首次报道，将Mo掺入[受电子邮件保护的]核-壳结构中可以显着提高AB水解产生氢的催化效率。Cu _0.81 @Mo _0.09 Co _0.10核壳催化剂对AB的水解脱氢表现出高催化活性，周转频率（TOF）值为49.6 molH ₂  mol _cat ^-1  min ^-1，它比以往报道的大多数基于铜的催化剂都高，甚至可以与基于贵金属的催化剂相媲美。优异的催化性能归因于三金属核-壳纳米粒子中铜，钼和钴的多元素共沉积效应和电子转移效应。
