CEROUS TUNGSTATE - Introduction
Tungsten cerium oxide (REO) is an oxide mixture composed of tungsten and cerium elements. It has the following properties:
1. High temperature stability: Cerium tungsten oxide has good stability at high temperature and can withstand chemical reactions and changes in physical properties in high temperature environments.
2. Catalytic performance: cerium tungsten oxide is widely used in the field of catalyst. It has excellent oxidation performance and adsorption capacity, and can be used for redox reactions in catalysts.
3. Photocatalytic properties: cerium tungsten oxide can also be used in photocatalytic reactions, which can absorb visible light and generate light-induced electron transmission, thereby promoting the occurrence of photocatalytic reactions.
4. Electrochemical properties: Tungsten cerium oxide shows good performance in electrochemistry and can be used in batteries and electrolytic batteries and other equipment.
The uses of tungsten cerium oxide include but are not limited:
1. Catalyst: used for oxidation-reduction and oxidation reactions in catalytic reactions.
2. Photocatalyst: used for environmental purification and wastewater treatment in photocatalytic reaction.
3. Electrochemical applications: used in lithium-ion batteries, fuel cells and electrolysis cells.
Methods for preparing tungsten cerium oxide generally include solid-phase methods, sol-gel methods, and hydrothermal methods. These processes may employ different reaction steps and process parameters depending on the needs and conditions.
Regarding the safety information of tungsten cerium oxide, the following matters need to be paid attention:
1. As a powder form, cerium tungsten oxide may form dust in the air. It is necessary to avoid inhalation and contact with skin and eyes. When using, wear personal protective equipment, such as respiratory protection, protective gloves, protective glasses, etc.
2. When handling and storing tungsten cerium oxide, avoid contact with other chemicals (especially oxidizing agents and reducing agents) to prevent dangerous reactions.
3. If tungsten cerium oxide is ingested or inhaled by mistake, seek medical attention immediately and show the product label and relevant safety information.
Before using tungsten cerium oxide, it is recommended to carefully read and follow the safety data sheet (SDS) and operating instructions provided by the supplier to ensure safe use.
