Molybdenum Phosphide powder is a grey-green, orthorhombic crystal system, stable at room temperature and pressure, insoluble in water but soluble in nitric acid, with highly efficient electrocatalytic properties.
Properties
Appearance and colour: grey-green powder.
Crystal structure: orthorhombic crystal system.
Density: Density about 6.58g/ml (20℃).
Melting point and boiling point: melting point is about 200.78℃, boiling point is about 511.30℃, but in practice, its stability at high temperature is better, and it can be used in a variety of chemical reactions and physical processes that require certain temperature conditions.
Hardness: relatively low Mohs hardness, soft texture, in some need to grind or mix the process, the softer texture makes it easier to mix with other substances.
Stability at room temperature and pressure: stable at room temperature and pressure, not easy to decompose naturally or react with common gases in the air.
Solubility: insoluble in water, but soluble in nitric acid, this solubility characteristics make it in some specific chemical treatment process, can be dissolved through nitric acid to achieve separation from other substances or related chemical reactions.
Oxidation: When heated to high temperature in air, it will have oxidation reaction with oxygen to produce corresponding oxides.
Acidity and alkalinity: Molybdenum Phosphide has certain chemical inertness itself, but under strong acidic or alkaline conditions, chemical reactions may occur, and the chemical bonds on its surface may be broken, thus affecting its physical and chemical properties.
Catalytic properties: Molybdenum Phosphide has good electrocatalytic properties and can be used as a highly efficient electrochemical catalyst for a variety of electrochemical reactions such as hydrogen precipitation reaction, carbon dioxide reduction, etc. It can effectively reduce the activation energy of the reaction and improve the reaction rate and selectivity.
Applications
Electrochemical field
Electrocatalytic hydrogen precipitation reaction: Molybdenum phosphide powder has excellent electrocatalytic properties, which can effectively reduce the activation energy of the hydrogen precipitation reaction, improve the reaction rate and efficiency, and can be used as a highly efficient catalyst in the process of hydrogen production by electrolysis of water to reduce the cost of hydrogen production, and promote the wide application of hydrogen energy.
Carbon Dioxide Reduction: Molybdenum Phosphide can be used to catalyse carbon dioxide reduction, converting carbon dioxide into valuable chemicals or fuels, such as carbon monoxide, formic acid, methanol, etc. It can help to reduce greenhouse gas emissions and achieve the effective use of carbon resources, which is of great significance in solving the energy and environmental problems.
Energy storage field
Electrode materials for lithium-ion batteries: Its good conductivity and chemical stability make it possible to be used as electrode materials or additives to electrode materials for lithium-ion batteries, improving the charging and discharging performance, cycle life, and energy density of batteries, and promoting the development of lithium-ion batteries in the fields of electric vehicles, portable electronic devices, and so on.
Chemical field
Catalyst carrier: Molybdenum Phosphide can be used as a catalyst carrier to improve the activity, selectivity and stability of the catalyst by loading other active components, widely used in petroleum refining, chemical synthesis and other reactions, such as hydrodesulfurisation, hydrodenitrogenation, aromatics hydrogenation and other reactions, which helps to improve the quality of chemical products, reduce production costs and reduce environmental pollution.
Phosphide agent: In some chemical reactions, it can be used as phosphide agent to provide phosphorus elements for other substances, participate in chemical reactions, and generate phosphide compounds with specific properties, which can be used for surface modification and functionalisation of materials.
Material science field
Composite material additives: added to polymer materials, ceramic materials or metal materials, as a reinforcing phase or functional phase, can improve the strength, hardness, abrasion resistance, corrosion resistance and other properties of the material, and at the same time give the material some special physical or chemical properties, such as electrical conductivity, magnetism, catalytic activity, etc., to expand the scope of application of the material.
Coating materials: Molybdenum Phosphide can be used to prepare coatings with special properties, such as wear-resistant coatings, anticorrosion coatings, self-lubricating coatings, etc. Through physical vapour deposition, chemical vapour deposition and other technologies, molybdenum phosphide powder is deposited on the surface of the material to form a layer of uniform, dense coating to improve the surface properties and service life of the material.
VI HALBLEITERMATERIAL GmbH (VIMATERIAL) employs a stringent quality assurance system to ensure the reliability of our product quality. Strict quality control is implemented throughout the entire production chain, and for defective products, we strictly enforce the principle of rework and redo. Each batch is released only after passing detailed specification tests.
Every batch of our materials is independently tested, and, if necessary, we send samples to certified companies for testing. We provide these documents and analysis certificates with the shipment to certify that our products meet the required standards.
