以纳米氧化镍为原料，采用一步退火法制备了孔径可调的纳米多孔镍。在原位形成的纳米多孔结构发生的顺序合作的表面上的氧化镍的还原和还原的镍在氢还原气氛下的各向异性重建。纳米孔结构内部的氧化镍骨架对抑制纳米孔结构的粗化起着重要作用。所得的可调纳米多孔镍提供了很好的理解在水电解中的析氢反应中的孔径依赖性。
A nanoporous nickel with tunable pore size was prepared with a one-step annealing method using nickel oxide nanoparticles. The in situ formation of nanoporous structures occurs by the sequential cooperation of reduction of nickel oxide on the surface and anisotropic reconstruction of reduced nickel under a hydrogen reductive atmosphere. The nickel oxide skeleton inside the nanoporous structures plays an important role to suppress coarsening of nanoporous structures. The resulting tunable nanoporous nickel provides good understanding of pore size dependence in the hydrogen evolution reaction in electrolysis of water.
