The development of high-efficiency and low-cost catalysts for hydrogen release from chemical hydrogen-storage materials is essential for the hydrogen-economy paradigm. Herein, we report a facile and controllable method to fabricate a series of Co-doped nickel phosphides and their corresponding nanohybrids with graphene oxide (GO) as highly efficient, robust and noble-metal-free catalysts for ammonia borane hydrolysis. The incorporation of Co into Ni₂P effectively optimizes the electronic structures of Ni_2−xCo_xP catalysts to enhance their interaction with AB and simultaneously facilitate the hydroxyl activation of AB, resulting in the reduction of the reaction energy barrier and thus substantial improvement of the catalytic rate.

Ni-Co-P三元纳米粒子作为无贵金属催化剂，可促进氨硼烷的水解脱氢

开发用于氢从化学储氢材料中释放氢的高效，低成本催化剂对于氢经济范式至关重要。在本文中，我们报告了一种简便且可控的方法，以制造一系列共掺杂的磷化镍镍及其相应的纳米杂化物和氧化石墨烯（GO），以作为高效，耐用且不含贵金属的氨硼烷水解催化剂。将Co掺入Ni ₂ P中可有效优化Ni _{2− x} Co _x P催化剂的电子结构，从而增强其与AB的相互作用，同时促进AB的羟基活化，从而降低了反应能垒，从而显着改善了催化速率。
