Abstract
Significant advancements have been made in the field of metal nanocatalysts for hydrogen (H2) release from ammonia borane (AB) hydrolysis. However, challenges persist in enhancing the rate of H2 release and the stability of materials through precise regulation of atom utilization in supported metal nanocatalysts. In this study, a self-mixed microporous carbon carrier (NPC) containing nitrogen (N) and phosphorus (P)was synthesized by activating adenosine triphosphate disodium (ATP), thereby eliminating the need for additional N and P sources. The synergistic effect of pore capture and N and P anchoring facilitated the successful preparation of RuCo alloys on the ATP-derived carbon support. Benefiting from the alloy effect of Ru and Co, the developed Ru1Co9/NPC catalyst achieved optimal catalytic performance, with a turnover frequency of 747.75 min−1, as well as favorable reusability for H2 release from AB. Furthermore, the incorporation of Zn2+ and EDTA-2Na enable control over the “ON-OFF” switch of AB as needed. This research not only presents a novel and efficient nanoalloy catalyst for AB hydrolysis but also establishes a viable method for on-demand H2 production.
