The development of low-cost catalysts with high activity and stability for the dehydrogenation of ammonia borane for hydrogen production becomes important in the field of heterogeneous catalysis. In this communication, an electromagnetic-field-assisted deposition process was adopted to prepare Ni foam supported CoCu alloy microspheres composed of nanosheets (CoCu/Ni). In the hydrolytic dehydrogenation of ammonia borane, the initial rate of hydrogen production for the as-prepared CoCu/Ni catalyst can reach 30.5 mol H₂ min⁻¹ mol_cat⁻¹. Moreover, the CoCu/Ni catalyst maintained its activity after 10 consecutive catalytic cycles, demonstrating its high stability and good reusability.

在多相催化领域中，开发具有高活性和稳定性的低成本催化剂以用于氨硼烷脱氢以生产氢气变得重要。在这种交流中，采用电磁场辅助沉积工艺来制备由纳米片（CoCu / Ni）组成的Ni泡沫负载的CoCu合金微球。在氨硼烷的水解脱氢中，如此制备的CoCu / Ni催化剂的氢产生的初始速率可以达到30.5mol H ₂ min ^-1 mol _cat ^-1。此外，CoCu / Ni催化剂在连续10次催化循环后仍保持其活性，证明了其高稳定性和良好的可重复使用性。
