The development of inexpensive and high performing catalysts for ammonia borane (NH₃BH₃) hydrolysis is crucial for hydrogen production. In our research, a high-performance plate-like Cu₂O–CoO nanocomposite catalyst for NH₃BH₃ hydrolysis has been developed for the first time. In the hydrolytic reaction, both Cu₂O and CoO are separately inactive, while Cu₂O–CoO nanoplates show a high turnover frequency of 34.1 mol_hydrogen min⁻¹ mol_cat⁻¹, which is attributed to the synergistic effect between Cu₂O and CoO. It is interesting to discover that the induction time for the hydrolytic reaction is reduced to null when a small amount of Cu₂O is introduced into CoO. The reaction kinetics of NH₃BH₃ hydrolysis catalyzed by Cu₂O–CoO is also investigated. This work may provide other researchers some valuable insights into designing inexpensive and synergistic catalysts with enhanced catalytic activity for NH₃BH₃ hydrolysis for hydrogen production.

廉价，高性能的氨硼烷（NH ₃ BH ₃）水解催化剂的开发对于制氢至关重要。在我们的研究中，首次开发了用于NH ₃ BH ₃水解的高性能板状Cu ₂ O–CoO纳米复合催化剂。在水解反应中，Cu ₂ O和CoO分别处于非活性状态，而Cu ₂ O–CoO纳米板的_氢转换频率很高，为34.1 mol_氢 min ^-1  mol _cat ^-1，这归因于Cu ₂之间的协同作用O和CoO。有趣的是，当将少量Cu ₂ O引入CoO时，水解反应的诱导时间减少为零。还研究了Cu ₂ O–CoO催化的NH ₃ BH ₃水解反应动力学。这项工作可能会为其他研究人员提供一些有价值的见识，以帮助他们设计出廉价且具有协同作用的催化剂，以增强对生成氨的NH ₃ BH ₃水解的催化活性。
