Recently, metal nanoparticles (NPs) have been investigated widely as heterogeneous catalysts in the hydrolysis of ammonia borane (AB). However, the method is severely challenged by the dispersion and particle size of metal NPs, and needs efficient carbon materials as supports. Herein, we describe a facile two‐step synthesis strategy that takes advantage of hydrothermal synthesis and solid‐phase carbonization to fabricate N‐doped bagasse‐derived carbon materials (BC‐hs). The Ru particles can disperse well on the BC‐hs carbon matrix to form Ru/BC‐hs catalyst. It is found that the Ru/BC‐hs catalyst, under optimized conditions (3.5 wt% Ru loading), shows a high performance for the catalytic dehydrogenation of AB, with a TOF of 354 mol H₂ (mol_Ru min)⁻¹. The high catalytic performance of Ru/BC‐hs may be ascribed to the large surface area of BC‐hs (2250 m²/g) with abundant surface nitrogen and oxygen species, and more catalytically active Ru atoms are provided with the fine‐grained and uniformly distributed Ru NPs. This study exhibits a universal method to design and prepare high‐performance dehydrogenation catalysts, in which metal NPs are supported on biomass‐derived carbon from a highly recyclable and available plant.

蔗渣衍生的碳载Ru纳米颗粒作为氨硼烷有效脱氢的催化剂

近年来，金属纳米颗粒（NPs）作为氨硼烷（AB）水解中的非均相催化剂已被广泛研究。然而，该方法受到金属NP的分散性和粒径的严重挑战，并且需要有效的碳材料作为载体。本文中，我们描述了一种简便的两步合成策略，该策略利用水热合成和固相碳化来制造N掺杂的甘蔗渣衍生碳材料（BC-hs）。Ru颗粒可以很好地分散在BC-hs碳基质上，形成Ru / BC-hs催化剂。发现Ru / BC-hs催化剂在最佳条件下（Ru负载量为3.5 wt％）显示出AB的催化脱氢的高性能，TOF为354 mol H ₂（mol _Ru min）^-1。Ru / BC-hs的高催化性能可能归因于BC-hs的大表面积（2250 m ² / g），且表面氮和氧种类丰富，并且细颗粒的Ru提供了更多的催化活性Ru原子。和均匀分布的Ru NP。这项研究展示了一种设计和制备高性能脱氢催化剂的通用方法，其中金属NPs负载在高度可回收利用的工厂的生物质衍生碳上。
