Description
Technical Field
The invention belongs to the technical field of electrocatalysis materials, and particularly relates to a multi-metal nitride heterojunction nanorod array composite electrocatalyst, and a preparation method and application thereof.
Background
The severe dependence on traditional fossil fuels presents an imminent source of energy and serious environmental problems for human society. One promising strategy to solve this problem is electrocatalytic water splitting to produce hydrogen, storing electrical energy in the chemical bonds of molecular hydrogen. And the hydrogen combustion product is water, is pollution-free and clean, and is an important component of future renewable energy sources. The water decomposition, the cathodic hydrogen evolution reaction and the anodic oxygen evolution reaction can also be driven by waste heat or renewable but intermittent wind energy or solar energy power generation.
The theoretical thermodynamic decomposition voltage of water is 1.23V in either acidic or basic environments. In practice, however, a much higher voltage than the theoretical value is required, and this difference is referred to as an overpotential. Thus, both reactions require an effective electrocatalyst to reduce overpotential, which promotes the slow kinetics of Oxygen Evolution Reaction (OER) or Hydrogen Evolution Reaction (HER) by reducing activation energy, making it widely used in industrial hydrogen production. The double-function electric catalyst has activity to two reactions, which simplifies the device and reduces the cost, and is more beneficial to the practical application. Fresh water widely used in laboratory electrolysis water research is a scarce resource in many parts of the world, and if electrochemical fresh water decomposition is carried out on a large scale, heavy pressure is exerted on important water resources. Seawater is one of the most abundant natural resources on the earth, accounts for 96.5 percent of the total amount of water resources in the world, and is almost an inexhaustible resource. In addition, the electrolysis of seawater is beneficial to environmental purification. Especially in arid regions, fresh drinking water can also be produced from seawater.
Therefore, it is very desirable to develop an efficient seawater electrolysis system for large-scale production of hydrogen, which is a revolutionary technology for sustainable hydrogen production and environmental remediation. However, achieving seawater splitting still has three major challenges. The first challenge is that the Oxygen Evolution Reaction (OER) which generates chlorine at the anode is competitive with the oxygen evolution reaction due to the presence of chloride ions in seawater. And the OER, chlorine and OH in alkaline environment - The voltage required for hypochlorite generation by the reaction is about 480mV higher than the anode OER driving 500 and 1000mA/cm 2 A high current density. The second challenge is that the inherently low conductivity of seawater leads to slow HER kinetics. A third challenge is that seawater is highly corrosive, the presence of non-harmful ions, bacteria, microorganisms and small particles in seawater, and the formation of insoluble precipitates (such as magnesium hydroxide and calcium hydroxide) covering the catalyst surface, all of which can poison OER and HER catalysts and destroy their long-term stability. Due to these troublesome problems, there is currently little research on bifunctional electrocatalysts for seawater cracking.
Therefore, the development of the bifunctional electrocatalyst with high performance, low cost and strong corrosion resistance for large-scale seawater cracking is of great significance. The Transition Metal Nitride (TMN) has good corrosion resistance, conductivity and mechanical strength, and is an ideal material for electrolytic seawater cracking. Nickel-based materials are the most commonly used electrocatalysts in alkaline electrolyzers. At present, metal oxides based on nickel, iron, cobalt, etc. exhibit excellent electrocatalytic oxygen evolution properties. While metal alloys based on nickel, iron, cobalt and the like have excellent performance on electrocatalytic hydrogen evolution, for example, the addition of Mo can optimize hydrogen adsorption on the alloy surface because Ni sites in the NiMo alloy can provide abundant water dissociation centers, so that the NiMo alloy has excellent activity and stability, and is widely researched. Moreover, in recent years, studies have shown that Ni 3 The ternary alloy of N/Ni, NiMoN and Ni-Fe-Mo has high catalytic activity in alkaline fresh water cracking.
Disclosure of Invention
The technical problem to be solved by the invention is to overcome the disadvantages mentioned in the backgroundThe invention provides a multi-metal nitride heterojunction nanorod array composite electrocatalyst, a preparation method and application thereof 4 The heterojunction nanorod array composite electrocatalyst obtained by depositing iron-based oxide on the nanorods and performing heating ammoniation treatment shows excellent OER and HER reaction activity in alkaline seawater and the like.
In order to solve the technical problems, the technical scheme provided by the invention is as follows:
a preparation method of a multi-metal nitride heterojunction nanorod array composite electrocatalyst comprises the following steps:
(1) NiMoO growth on foamed nickel by hydrothermal reaction 4 A nanorod; in NiMoO 4 Depositing iron-based oxide on the nanorods to obtain a nickel-molybdenum-iron oxide precursor/foamed nickel composite material;
(2) and carrying out thermal amination treatment on the nickel-molybdenum-iron oxide precursor/foamed nickel composite material to obtain the multi-metal nitride heterojunction nanorod array electrocatalyst.
In the preparation method, in the step (1), NiMoO is grown on the foamed nickel by adopting a hydrothermal reaction 4 The nanorod specifically comprises the following steps: dissolving 0.04mol/L nickel salt and 0.01mol/L molybdenum salt in water to obtain a solution; putting the solution into a high-pressure kettle, soaking foamed nickel into the solution, carrying out hydrothermal reaction at 150 ℃ for 8 hours, cooling to room temperature, taking out the foamed nickel, and drying to obtain the NiMoO 4 Foamed nickel of nanorods.
