NiFe氢化酶是催化H+/H-2相互转化的独特酶，具有显著的效率。三维结构的活性中心（富硫双核镍-铁簇与双原子氰化物和羰基配体）的测定刺激了各种镍基配合物作为潜在的电催化剂用于制氢的合成。这些催化剂可提供铂的适当替代物。本文给出了一个历史的角度来看，这种仿生结构的方法，然后集中在最近报道的生物启发的功能模拟显示电催化活性制氢。
NiFe hydrogenases are unique enzymes that catalyze the H+/H-2 interconversion with remarkable efficiency. The determination of the tridimensional structure of their active site (a sulfur-rich dinuclear nickel-iron cluster with diatomic cyanide and carbonyl ligands) has stimulated the synthesis of a variety of nickel-based complexes as potential electrocatalysts for hydrogen production. These catalysts may provide an adequate alternative to platinum. This paper gives an historical perspective of this biomimetic structural approach and then focusses on recently reported bio-inspired functional mimics displaying electrocatalytic activity for hydrogen production.
