Self-supporting integrated electrode material derived from wood charcoal as well as preparation method and application of self-supporting integrated electrode material
The invention belongs to the technical field of electrode materials, and discloses a self-supporting integrated electrode material derived from wood charcoal and a preparation method and application thereof, and the preparation method of the material comprises the following steps: S1, preparing three-dimensional porous wood charcoal derived from poplar wood charcoal; s2, preparing a mixed solution containing a nickel source and a molybdenum source; s3, preparing an electrode material precursor of molybdenum-nickel oxide growing on the wood charcoal by using the three-dimensional porous wood charcoal and the mixed solution; and S4, performing high-temperature reduction on the precursor to obtain the self-supporting integrated electrode material derived from the wood charcoal. The invention also discloses application of the electrode material in water electrolysis hydrogen production. The electrode material is synthesized by adopting a hydrothermal synthesis method and a high-temperature hydrogen mixed gas reduction method, the obtained molybdenum-nickel alloy is embedded into a heterostructure of molybdenum dioxide and grows on the wood charcoal in situ, and the rapid substance transfer of the porous wood charcoal structure is combined, so that the electronic structure can be adjusted, and the water dissociation energy barrier is reduced; and the composite material has excellent electrocatalytic activity and stability on an electrolytic water reaction under an alkaline condition..
