What are the Challenges in Using Catalysts in Gas Sensors?
Despite their advantages, there are several challenges associated with using catalysts in gas sensors:
- Cost: Noble metals like Pt and Pd are expensive, which can increase the overall cost of the sensor. - Stability: Catalysts can degrade over time due to factors like sintering and poisoning, affecting the sensor’s longevity. - Complexity: Integrating catalysts into sensor materials can be complex and may require advanced fabrication techniques.
