What are the Key Characteristics of Catalytic Materials?
When selecting materials for catalysis, several key characteristics must be considered to ensure optimal performance:
1. Activity: The material must exhibit high catalytic activity to accelerate the desired chemical reaction. 2. Selectivity: It should selectively catalyze the intended reaction without promoting undesired side reactions. 3. Stability: The catalyst must sustain its activity and selectivity over a prolonged period under reaction conditions. 4. Surface Area: High surface area enhances the availability of active sites for the reaction. 5. Thermal and Chemical Resistance: The material should withstand high temperatures and corrosive environments.
