Fluorinated Metal Oxides

Fluorinated Metal Oxides

Introduction

Fluorinated metal oxides are special compounds containing two different anions. Since the ionic radii of fluoride ions and oxygen ions are similar, fluoride ions and oxygen ions are easily doped with each other, resulting in some distinctive properties, such as electrical conductivity. Fluorinated metal oxides are widely used in production and life. They can be used as gas-sensing materials, electrode materials, nanomaterials and catalysts. With the deepening of its research, more and more fluorinated metal oxides have been developed and utilized.

Applications

Fluorinated metal oxides are widely used as materials and catalysts due to their excellent properties.

• Materials. Fluorinated metal oxides are widely used as gas-sensitive materials, electrode materials and nanomaterials. When they are used as gas-sensing materials, fluorinated metal oxides can capture water molecules by forming hydrogen bonds, which is conducive to the adsorption and reaction of gas molecules on the surface of the material, thereby improving the humidity stability of materials and making them suitable for use in high-humidity environments. Fluorinated metal oxides are also commonly used as anode materials for energy storage devices such as lithium-ion batteries, lithium batteries, lithium-air batteries, lithium-sulfur batteries and supercapacitors because of their excellent cycle performance and high electronic conductivity. In addition, when fluorinated metal oxides are used as nanomaterials, they are widely used in the fields such as electrochemistry, glass, ceramics, etc. due to their advantages of small particle size, uniform distribution and good dispersion stability and their properties of hydrophobicity, oleophobicity, and anti-fingerprint.

• Catalysts. Fluorinated metal oxides are an important class of catalysts and have been widely used in the field of catalysis. For example, in terms of water pollution treatment, catalytic ozone oxidation technology is widely used. The addition of fluorinated metal oxides as catalysts enables rapid decomposition of ozone to generate hydroxyl radicals with strong oxidizing ability, thereby degrading organic pollutants into easily biochemical small molecule intermediates and achieving the purpose of purifying water. Therefore, fluorinated metal oxides have been used as green, economical, efficient and environmentally friendly catalysts for water pollution treatment.
