What Are the Challenges in Using Catalysts in Air Quality Sensors?
While catalysts offer numerous benefits, there are also challenges associated with their use in air quality sensors:
1. Deactivation: Over time, catalysts can lose their activity due to poisoning by other chemicals or the accumulation of reaction by-products. 2. Cost: Noble metal catalysts, although effective, are expensive and may not be cost-effective for widespread use. 3. Stability: Catalysts must be stable under the operating conditions of the sensor, including temperature, humidity, and the presence of other gases.
