OXYGEN EVOLUTION REACTION CATALYST, PREPARATION METHOD THEREFOR, AND USE THEREOF

Resumen de: WO2025162048A1

The present application belongs to the technical field of hydrogen production by water electrolysis, and particularly relates to an oxygen evolution reaction catalyst, a preparation method therefor, and the use thereof. The present application uses the hydrolysis effect of metal positive ions in a hydrolysable metal salt solution to make a weakly-acidic heterogeneous soaking system, which slowly acts on the surface of a metal substrate, thereby partially etching the surface of the metal substrate while removing metal oxides on the surface; on the surface of the substrate, metal ions generated by the etching bind to metal ions generated by hydrolysis, so as to form an LDH catalyst structure, ensuring a relatively high catalytic activity thereof. Moreover, under an interface-confined effect, a compact transition layer structure is slowly formed at the interface between the metal substrate and the catalyst layer; as a bridge of the metal substrate and the catalyst layer, said transition layer has the same structure as that of the LDH, but exhibits a more compact appearance and totally covers the surface of the metal substrate, so as to firmly anchor the LDH catalytic structure layer onto the surface of the metal substrate, thereby allowing the OER catalyst to have high activity and high stability under the condition of an industrial-level current density.

Compared with the existing practice of welding a pipeline at fluid inlet/outlets, the fluid inlets/outlets in the annular frame body of the present application do not need welding and have no welding spot, thereby preventing generation of stress corrosion, further preventing the phenomenon of galvanic corrosion caused by a welding material being different from materials of a pipeline and an electrode plate frame during welding, and reducing the risk of leakage at the joint of the electrode plate frame and the external pipeline.
