In the field of modern electrochemistry, Ruthenium-Iridium-titanium anodes play a key role in many industrial production and scientific research fields due to their unique properties. The electrolysis principle mainly revolves around a series of complex and delicate electrochemical reactions, which usually occur in a specific environment of an electrochemical cell or electrolytic cell.
The constituent elements of the ruthenium-iridium-titanium anode include ruthenium (Ru), iridium (Ir) and titanium (Ti). Among them, ruthenium and iridium work together to give the anode excellent corrosion resistance. In practical applications, the electrochemical environment is often full of various corrosive media, such as strong acidic and alkaline solutions. Ordinary materials are easily corroded in such an environment, which affects the service life and electrolysis efficiency of the anode. Ruthenium-iridium alloys can effectively resist these corrosion effects and ensure that the anode maintains stable performance during long-term electrolysis. At the same time, titanium, as the base material of the anode, provides the necessary strength for the entire structure, enabling it to withstand the mechanical stress during the production process. More importantly, titanium has good electrical conductivity, which is crucial for efficient transmission of current and ensuring the smooth progress of electrolysis reactions. In the entire anode system, different elements perform their respective functions and jointly build a stable and efficient electrolysis reaction platform.
During the electrolysis process, the coating on the anode surface plays a critical catalytic role. When in a specific electrolyte environment, the coating can cause chloride ions or water molecules to lose electrons, thereby generating products such as chlorine or oxygen. This process can be subdivided into chlorine evolution reaction and oxygen evolution reaction, which have extensive and important applications in different industrial scenarios.
Chlorine evolution reaction
In hydrochloric acid environments and systems with high chloride ion content such as electrolysis of seawater and electrolysis of salt water, ruthenium iridium titanium anodes will undergo chlorine evolution reactions. This reaction occupies a core position in the chlor-alkali industry. Taking the large-scale production of the chlor-alkali industry as an example, by electrolyzing saturated salt water, not only can chlorine be efficiently produced, but also caustic soda (sodium hydroxide), an important chemical raw material, can be obtained. In the actual production process, the use of ruthenium iridium titanium anodes can significantly improve the efficiency and stability of the chlorine evolution reaction. At the same time, due to its good corrosion resistance, the service life of the anode is greatly extended from several months to several years, effectively reducing equipment maintenance costs and production interruption risks.
Oxygen evolution reaction
In the electrolytic refining process of some metals, oxygen evolution reaction plays an important role. For example, in the electrolytic refining of copper, crude copper is used as the anode. During the electrolysis process, in addition to the copper atoms losing electrons and dissolving into the solution, some impurities in the anode (such as iron, zinc, etc.) will also undergo oxidation reactions. The oxygen evolution reaction of the anode can create an oxidizing environment, prompting some impurities that are difficult to directly oxidize and dissolve (such as certain metal oxides) to undergo further reactions, thereby falling off from the anode and entering the electrolyte, and finally being removed through subsequent purification processes, effectively improving the purity of the cathode copper. In practical applications, by reasonably adjusting the coating formula of the ruthenium-iridium-titanium anode and the electrolysis process parameters, the rate and degree of oxygen evolution reaction can be accurately controlled to meet the needs of different metal refining processes.
