在酸性条件下，对含硼三(乙二酮亚胺)钴络合物的电化学研究表明，在适当的阴极电位下，含钴纳米颗粒在电极表面的电沉积是催化析氢活性的结果。在pH值为7的水中，沉积的颗粒对H-2的生成具有显著的催化活性。
Electrochemical investigation of a boron-capped tris(glyoximato)cobalt clathrochelate complex in the presence of acid reveals that the catalytic activity toward hydrogen evolution results from an electro-deposition of cobalt-containing nanoparticles on the electrode surface at a modest cathodic potential. The deposited particles act as remarkably active catalysts for H-2 production in water at pH 7.
