The choice of form depends on factors such as the specific electrochemical reaction, the required surface area, the geometry of the electrolyte cell, and the desired efficiency. Additionally, coatings of noble metals like platinum, ruthenium, or iridium oxide are often applied to these titanium forms to enhance their electrocatalytic properties and improve their performance in various electrochemical processes.
Titanium is used as an anode in the electrolysis of brine due to its excellent reduction resistance and suitability for electrolytes with low chloride ion concentration. It allows for pole reversal during electrolysis and provides an effective chlorine separation. Additionally, the oxygen separation potential of titanium anodes is higher than that of ruthenium, enhancing efficiency and durability.
Coatings on titanium anodes enhance their electrocatalytic properties, improving their performance in specific electrolytic processes and increasing their efficiency.
Titanium cathode plates are used as negative electrodes in various electrowinning processes, offering good corrosion resistance and improved service life. Anodes, on the other hand, are used as positive electrodes and typically have coatings for specific electrochemical reactions.
Titanium electrodes, coated with a precious metal, are used in electrolysis to produce dissolved oxygen. Unlike copper electrodes, they do not lose mass or degrade over time, ensuring consistent performance. Their size and shape remain unchanged, providing long-lasting durability and efficiency in various electrochemical applications.
