What Types of Catalysts Are Commonly Used in Air Quality Sensors?
Several types of catalysts are used in air quality sensors, including:
1. Metal-Oxide Catalysts: Common metal oxides like titanium dioxide, zinc oxide, and tin dioxide are widely used due to their high surface area and excellent reactivity. 2. Noble Metal Catalysts: Platinum, palladium, and gold are used for their superior catalytic properties, despite being more expensive. 3. Zeolite Catalysts: These microporous materials can trap gases and facilitate their interaction with active sites.
