Violet tungsten is a tungsten oxide compound with special color, and its chemical formula is WO2.72. Its color is due to defects in its crystal structure and changes in oxidation state. Violet tungsten dispersion is a suspension formed by dispersing violet tungsten powder in an appropriate solvent. Commonly used solvents include water and other polar solvents. The dispersion state of violet tungsten particles can be achieved by proper dispersion techniques, such as stirring, ultrasonic treatment, etc.
Violet tungsten dispersions are widely used in research and application, especially in the fields of photocatalysis, electrocatalysis, and energy storage. Due to its special optical and electronic properties, violet tungsten has been widely studied for photocatalytic reactions, photovoltaic cells, and electrochemical catalysis. By adjusting the concentration, pH value and other processing parameters of the violet tungsten dispersion, the particle size, shape and dispersion can be controlled to meet the needs of specific applications.
