Document Type and Number:
Japanese Patent JP7434372
Kind Code:
B2
Abstract:
The present disclosure discloses a nickel-iron catalytic material, a preparation method thereof, and a use thereof in the hydrogen production through water electrolysis and the preparation of a liquid solar fuel (LSF). The nickel-iron catalytic material is prepared by using a soluble iron salt as a raw material and growing on a modified nickel substrate under mild conditions, and the nickel-iron catalytic material can be used in the industrial alkaline water electrolysis under harsh conditions. The nickel-iron catalytic material includes a nickel metal substrate and a catalytically-active layer with iron and nickel. When used to promote a water splitting reaction, the nickel-iron catalytic material of the present disclosure can reduce the energy consumption per m3 of hydrogen production through industrial alkaline water electrolysis from 4.4 kWh to 4.01 kWh, thereby increasing the conversion of solar energy to methanol by 9.7%. The nickel-iron catalytic material involves a simple preparation process and low cost, and can easily realize the industrial scale-up preparation. Through this process, solar energy can be converted into a conventional fuel that can be conveniently stored and transported, which provides a new way to solve energy and environmental problems, and brings huge economic and social benefits.
