The development of highly active and stable catalysts is desirable for hydrogen generation from ammonia borane (AB). In this study, Ni_0.25Co_0.75O nanowire array supported on Cu@CuO foam (Ni_0.25Co_0.75O/Cu@CuO) has been successfully fabricated. The Ni_0.25Co_0.75O/Cu@CuO catalyst exhibited high performance towards AB hydrolysis with a high hydrogen generation rate (HGR) of 4.348 L_hydrogen min⁻¹ g_cat.⁻¹. More importantly, the activity of Ni_0.25Co_0.75O/Cu@CuO has only decreased slightly after twelve cycles. This work provides a simple method to fabricate an inexpensive film catalyst with high activity and good stability for ammonia borane hydrolysis.

开发高活性和稳定的催化剂是氨硼烷（AB）制氢所需要的。在这项研究中，已成功制造出负载在 Cu@CuO 泡沫上的Ni _0.25 Co _0.75 O 纳米线阵列（Ni _0.25 Co _0.75 O/Cu@CuO）。Ni _0.25 Co _0.75 O/Cu@CuO 催化剂对 AB 水解表现出高性能，具有 4.348 L_氢min ^-1 g _cat的高产氢率 (HGR) _。^-1。更重要的是，Ni _0.25 Co _0.75的活性O/Cu@CuO 在十二个循环后仅略有下降。这项工作提供了一种简单的方法来制备廉价的薄膜催化剂，该催化剂具有高活性和良好的氨硼烷水解稳定性。
