Ammonium metatungstate dispersion in the field of new energy applications are mainly reflected in the catalyst and material preparation of two aspects, the following are specific application examples:
- Catalyst application
Biodiesel production
Ammonium metatungstate has been used as palm oil hydrogenation catalyst to produce biodiesel. This catalyst can significantly improve the oxidative stability, cetane number and cold flow characteristics of biodiesel, making it a more environmentally friendly and efficient energy alternative.
Hydrogenation Electrocatalysts
Ammonium metatungstate also has important applications in hydrogen precipitation electrocatalysts. For example, it can be combined with Pt nanoparticles to form high-performance hydrogen precipitation electrocatalysts. Such catalysts exhibit excellent activity and stability in the hydrogen precipitation reaction, which can help promote the development of new energy technologies such as hydrogen production from electrolyzed water.
Hydrogen production catalyst
Ammonium metatungstate has also been used to prepare tungsten phosphide nanorods (WP2), a material with high catalytic potential for hydrogen production. The tungsten phosphide nanorods exhibit excellent catalytic activity and durability in acidic, neutral and alkaline media, and are expected to be an alternative to platinum-based catalysts for large-scale hydrogen production.
- Material Preparation
High purity tungsten products
Ammonium metatungstate is a reducing agent that can reduce tungsten oxide to tungsten metal. This property makes ammonium metatungstate play an important role in the preparation of high-purity tungsten products such as tungsten wires, tubes and rods. These high-purity tungsten products are widely used in new energy fields, such as solar cells and nuclear fusion reactors.
High-temperature and corrosion-resistant materials
Ammonium metatungstate has excellent high-temperature stability and corrosion resistance, and these properties make it an ideal raw material for the preparation of high-temperature and corrosion-resistant materials. In the field of new energy, these materials can be used to manufacture components for fuel cells, energy storage systems and other equipment to improve the reliability and service life of the equipment.
Third, other applications
Although the application of ammonium metatungstate dispersion in the field of new energy mainly focuses on catalyst and material preparation, with the continuous development of new energy technology, the application potential of ammonium metatungstate in other aspects is also gradually emerging. For example, it may be used in the preparation of new battery materials, photoelectric conversion materials, etc., in order to promote the further innovation and development of new energy technology.
Ammonium metatungstate dispersion has a wide range of application prospects in the field of new energy, and its unique physicochemical properties make it one of the important materials to promote the development of new energy technology.
