Iridium catalysts are distinguished by their long service life, which is a critical factor in their widespread use in industrial applications. Several factors contribute to this extended lifespan:
High Thermal Stability: Iridium maintains its catalytic properties even at high temperatures, making it suitable for processes requiring elevated temperatures.
Resistance to Chemical Wear: Its resistance to corrosion and chemical wear extends its operational life, especially in harsh chemical environments.
Efficiency Over Time: Iridium catalysts tend to maintain their efficiency over time, reducing the need for frequent replacements.
Stability of Iridium Catalysts
The stability of a catalyst is essential for consistent performance, and iridium excels in this aspect:
Chemical Stability: Iridium is less prone to poisoning by impurities compared to other catalysts, maintaining its activity over prolonged periods.
Physical Stability: It resists physical changes under reaction conditions, ensuring consistent catalytic activity.
Comparative Perspective
When compared to other catalysts like platinum or palladium, iridium's superior thermal and chemical stability often translates into a longer service life, though it may come at a higher cost.
