Amorphization-induced abundant coordinatively unsaturated Ni active sites in NiCo(OH)2 for boosting catalytic OER and HER activities at high current densities for water-electrolysis

With rich corner sites and edge sites, the amorphous-crystalline NiCo(OH)2 catalyst exhibits superior catalytic OER and HER activities at high current densities since the amorphization can promote the partial electron transfer from Co to Ni species and result in the tensile Ni-O bonds. The coordinat...
