合成了三维氮掺杂石墨烯基骨架（NiNPs@3D-（N）GFs）负载的镍纳米颗粒，并研究了其在氨硼烷水解脱氢中的制氢性能. NiNP在3D-（N）GF上的高度分散以及3D-（N）GF和NiNP之间的巩固的相互作用催化氢分子的解离和随后的氢原子在3D-（N）GF上的迁移。由于所制备的材料的独特性质，如多孔结构和氮和镍的存在与分子氢相互作用，它具有很高的潜力，用于储氢。所制备的催化剂是开发高效便携式制氢的理想候选物，其可用于燃料电池、金属/空气电池等各种应用。
Nickel nanoparticles immobilized on three-dimensional nitrogen-doped graphene-based frameworks (NiNPs@3D-(N)GFs) were synthesized and examined for hydrogen generation from the hydrolytic dehydrogenation of ammonia borane. The high dispersion of NiNPs over the 3D-(N)GFs and consolidated interaction between the 3D-(N)GFs and NiNPs catalyzes the dissociation of hydrogen molecules and the subsequent migration of hydrogen atoms on the 3D-(N)GFs. Due to the unique properties of the as-prepared material such as porous structure and existence of nitrogen and nickel to have interaction with molecular hydrogen, it has high potential to be employed in hydrogen storage. The as-prepared catalyst is an ideal candidate for developing highly efficient portable hydrogen generation, which can be useful for various applications such as fuel cells, metal/air batteries, etc.
