High-purity molybdenum trioxide MoO3 has two main application directions in the field of functional materials: new energy batteries and petrochemical catalysis.

The layered structure of pure molybdenum trioxide MoO3 allows lithium ions to be inserted and removed from between layers of the material, so it has attracted attention in lithium battery applications. At the same time, this structure also provides active sites for catalytic reactions, so it is also an important raw material for hydrodesulfurization catalysts.

1. Basic Situation of High-Purity Molybdenum Trioxide MoO3

High-purity molybdenum trioxide MoO3 is a white to light green or light gray crystalline powder. Its molecular weight is 143.94, its density is 4.6926 g/cm³, its melting point is 795℃, and its boiling point is 1155℃ (sublimation). It stabilizes in the air. It is slightly soluble in water, and when dissolved in water, molybdenum acid is formed. It is easily soluble in ammonia, soda ash, caustic soda, hydrofluoric acid and concentrated sulfuric acid, and is insoluble in ordinary acids.

High-purity molybdenum trioxide MoO3 has three structural forms: orthorhombic phase α-MoO3, monoclinic phase β-MoO and high-pressure phase MoO3. Among them, the layered structure of the orthorhombic phase α-MoO3 is the most important feature. Specifically, this layered structure consists of co-sided MoO3 octahedra, and the layers are bonded to each other by van der Waals forces. Lithium ions can be inserted into or removed from the layers. At the same time, the exposed surface atoms of this structure provide active sites for catalytic reactions.

These structural characteristics determine that high-purity molybdenum trioxide MoO3 has application value in both catalysis and lithium batteries.

2.Application of High-Purity Molybdenum Trioxide Moo3 in Catalyst Field

Why use high-purity molybdenum trioxide MoO3 as as the catalyst？

During petroleum refining, crude oil contains sulfur. If sulfur is not removed, pollutants will be produced after combustion. Therefore, refineries use hydrodesulfurization (HDS) catalysts to remove sulfur from oil products.

Pure molybdenum trioxide MoO3 is one of the important raw materials for hydrodesulfurization catalysts. After it is mixed with metal compounds such as nickel and cobalt, it will form an active catalytic phase after high temperature treatment. This catalytic phase can promote the sulfur removal reaction.

Current global environmental protection regulations require increasingly strict sulfur content in fuels. Refiners need to reduce diesel sulfur concentrations to lower levels. This trend has driven the growth in demand for catalyst-grade high-purity molybdenum trioxide MoO3. In the chemical field, catalysts are one of the main uses of molybdenum trioxide.

What are the requirements for high-purity molybdenum trioxide MoO for catalysts？

After understanding why high-purity molybdenum trioxide MoO3 is used as a catalyst, what specific indicators should you pay attention to when purchasing?

The procurement indicators of catalyst-grade high-purity molybdenum trioxide MoO3 mainly include:

· Particle size: Particles should be within a specific size range, and the size of some particles needs to be concentrated in the target range. This is directly related to the activity of the catalyst.

· Purity: Low impurity content is a basic requirement to ensure catalyst activity.

· Pore structure: The catalyst needs to have a suitable pore structure. The size and distribution of pores can affect the efficiency of contact between the reactants and the catalyst.

The purity of high-purity molybdenum trioxide MoO3 produced by Hongtuo can reach 99.95%. The company adopts wet chemical purification and high-temperature roasting processes, which can effectively remove impurities such as iron, silicon, and calcium. After the impurity content is reduced, interfering factors in the downstream catalyst production process are also reduced.

Hongtuo's products are suitable for various reduction processes such as hydrogen reduction, electrolysis and leaching. The company can adjust parameters such as particle size and specific surface area according to customers 'specific requirements. Hongtuo can also provide customers with technical information and export certification, and can also cooperate in developing products of special specifications.

Hongtuo directly uses high-purity molybdenum trioxide powder as raw material and does not use molybdenum salt compounds. This helps avoid the introduction of additional impurities and simplifies the catalyst preparation process.

3. Application of High-Purity Molybdenum Trioxide MoO3 in the Field of Lithium Batteries

Why do lithium batteries use high-purity molybdenum trioxide MoO3？

Currently, lithium batteries mainly use graphite as the anode material. The capacity of graphite is approaching its theoretical limit, and researchers are looking for new materials to further increase battery capacity.

Pure molybdenum trioxide MoO3 is one of the materials that has attracted attention. Its theoretical capacity is higher than that of graphite, and its layered structure is conducive to the insertion and disengagement of lithium ions. Therefore, it is being studied as one of the candidates for the next generation of anode materials.

During the charge and discharge process, molybdenum ions of high-purity molybdenum trioxide MoO3 can change between multiple valence states and can undergo multiple electron transfer reactions, thus providing a higher charge storage capacity. Some studies have shown that MoO3 nanoelectrode materials have high primary discharge capacity and can remain stable in subsequent cycles.

What is the difference between nanometer molybdenum trioxide and micron molybdenum trioxide？

In addition to the properties of the material itself, the size of the material will also affect the performance.

Preparing materials to nanoscale is one of the ways to improve the electrochemical properties of MoO3. Academic research compares the performance of nano MoO3 and micron MoO3 in lithium batteries:

The advantages of nanoscale are reflected in two aspects. First of all, the nanoscale particles have small size, short lithium ion diffusion paths, and fast insertion and disengagement speeds. Secondly, nanoscale particles have a large specific surface area and can provide more reaction sites. These two factors work together to improve the insertion and removal efficiency of lithium ions during the charge and discharge process.

Buyers in the lithium battery field usually pay attention to purity and particle size distribution when selecting high-purity molybdenum trioxide MoO3. The higher the purity, the less the impact of impurities on battery performance. Only when the particle size is appropriate can the nanocomposite materials with good properties be prepared.

Hongtuo can provide high-purity molybdenum trioxide MoO3 with a purity of more than 99.95%. The particle size can be adjusted according to customers 'nanoscale or composite process requirements. The company also provides technical docking services to help customers optimize application solutions.
