Title:
METAL-ORGANIC FRAMEWORK-BASED WATER ELECTROLYSIS CATALYST DERIVED FROM PRUSSIAN BLUE ANALOG COMPRISING THREE TRANSITION METALS AND COMPRISING SIZE-CONTROLLED PORES, AND METHOD OF PREPARING SAME
Document Type and Number:
WIPO Patent Application WO/2020/080637
Kind Code:
A1
Abstract:
Disclosed is a metal-organic framework-based water electrolysis catalyst prepared from a Prussian blue analog. The metal-organic framework-based water electrolysis catalyst comprises, as transition metals, Ni having an oxidation number of 2, Co having an oxidation number of 2, Co having an oxidation number of 3, Fe having an oxidation number of 2, and Fe having an oxidation number of 3, and comprises a coordination compound in which [Co(CN)6]3- complex ions are bonded to Ni2 +, a coordination compound in which [Fe(CN)6]3- complex ions are bonded to Ni2 +, and NiS produced by an ion-exchange reaction of the [Co(CN)6]3- complex ions and S2- ions.
