Embodiment Construction

[0046] Below, the technical solution of the present invention will be described in detail through specific examples.

[0047] 1. Experimental method

[0048] 1. Characterization of samples

[0049] The compositional structure of the samples was characterized by using X-ray diffraction equipped with Cu Kα (λ = 0.154 nm) on a Smart lab SE diffractometer. The morphology of the samples was observed by scanning electron microscope and transmission electron microscope. X-ray photoelectron spectroscopy was used to characterize the composition and bonding state of the sample. All test results were calibrated for all element spectra using C1s (284.8eV) as the standard peak.

Abstract

The invention discloses an N and P co-doped NF@NiMoO4 hollow nanowire composite material and a preparation method thereof, and the preparation method comprises the following steps: S1, dissolving a soluble nickel salt and a soluble molybdenum salt in deionized water to obtain a mixed solution; S2, soaking foam nickel in the mixed solution for a hydrothermal reaction, and obtaining an NF@NiMoO4 precursor; and S3, calcining the NF@NiMoO4 precursor, a nitrogen source and a phosphorus source in a protective atmosphere to obtain the N and P co-doped NF@NiMoO4 hollow nanowire composite material. The invention further discloses application of the N and P co-doped NF@NiMoO4 hollow nanowire composite material as a catalyst for electro-catalysis water decomposition and hydrogen evolution reaction.

Description

technical field [0001] The invention relates to the technical field of electrocatalysis, in particular to a kind of N, P co-doped NF@NiMoO 4 Hollow nanowire composite material and its preparation method and application. Background technique [0002] In the context of energy shortage and environmental crisis, the development of clean, environmentally friendly, pollution-free and renewable alternative energy sources, such as solar energy, wind energy, hydrogen energy, etc., can effectively reduce the demand for fossil fuels. As a renewable energy source, hydrogen energy has the advantages of abundant resources and easy storage. Meanwhile, hydrogen production from water electrolysis is considered to be an effective strategy for converting and storing large-scale renewable energy. The electrocatalytic water splitting technology involves two half-reactions: the hydrogen evolution reaction (HER) that occurs at the cathode and the oxygen evolution reaction (OER) that occurs at th...
