Metal nanoparticles (NPs) deposited on nitrogen (N)- and/or phosphorus (P)-doped porous carbon have been investigated as efficient catalysts for hydrolysis of ammonia borane (AB). However, the one-pot synthesis of N,P co-doped porous carbon using low-cost and readily available sources is still a tremendous challenge. Herein, a novel one-pot methodology is developed to fabricate N and P co-doped porous carbon (ATP-C) using non-precious and easily available adenosine triphosphate (ATP). The process of N and P doping does not need additional N or P sources in the material. Moreover, the entire process did not require chemical activation agents, making it more practical for large-scale applications. The resulting ATP-C supported Rh NPs (Rh/ATP-C) exhibit excellent performance for the catalytic hydrolysis of ammonia borane toward hydrogen generation, with a total turnover frequency (TOF) value of 566 mol H2 min−1 (mol Rh)−1 and activation energy (Ea) of 26.3 kJ mol−1. The catalytic system has shown an outstanding catalytic cycle life during the recycling tests. This work provides a novel method for the production of high performance carbon material supported metal NP catalysts for practical dehydrogenation applications.

一种简单直接的合成 N,P 共掺杂多孔碳的策略:一种用于氨硼烷脱氢和催化应用的 Rh 纳米颗粒的有效载体

已经研究了沉积在氮 (N) 和/或磷 (P) 掺杂的多孔碳上的金属纳米粒子 (NP) 作为氨硼烷 (AB) 水解的有效催化剂。然而,使用低成本和容易获得的来源一锅法合成 N、P 共掺杂多孔碳仍然是一个巨大的挑战。在此,开发了一种新的一锅法,使用非贵重且易于获得的三磷酸腺苷 (ATP) 制造 N 和 P 共掺杂多孔碳 (ATP-C)。N和P掺杂的过程不需要材料中额外的N或P源。此外,整个过程不需要化学活化剂,使其更适合大规模应用。得到的 ATP-C 负载的 Rh NPs (Rh/ATP-C) 在氨硼烷催化水解制氢方面表现出优异的性能,2 min -1 (mol Rh) -1和26.3 kJ mol -1的活化能( E a ) 。该催化系统在回收测试中表现出出色的催化循环寿命。这项工作为生产用于实际脱氢应用的高性能碳材料负载金属NP催化剂提供了一种新方法。
