Abstract

The invention discloses a FeNiNC electrode material as well as a preparation method and application of the electrode material. The preparation method comprises the following steps: firstly, mixing ferric nitrate nonahydrate, urea, trisodium citrate and water, and performing hydrothermal reaction on the mixed solution so as to generate colloid; soaking foamed nickel into the colloid, and after soaking is completed, drying the foamed nickel in a vacuum drying oven; and finally performing calcining, thereby obtaining the FeNiNC electrode material. The FeNiNC electrode material disclosed by the invention is of a floppy porous structure similar to the foamed nickel, is low in raw material cost and good in hydrogen separation effect and has the potential of industrial development.

Description

technical field [0001] The invention relates to the technical field of hydrogen energy, in particular to a FeNiNC electrode material, a preparation method and an application thereof. Background technique [0002] Energy and the environment are the most important issues involved in the sustainable development of human society. At present, 80% of the world's energy demand comes from fossil fuels, which will eventually lead to the depletion of fossil fuels, and their use will also lead to serious environmental pollution. It is an inevitable trend of development to gradually shift from fossil fuels to non-fossil energy sources with sustainable development and pollution-free. Hydrogen is one of the ideal clean energy sources and also a heavy chemical raw material, which is widely valued by countries all over the world. Hydrogen production by electrolysis of water is an important means to achieve industrialization and low-cost production of hydrogen. Hydrogen production by elec...
