Several factors can affect the stability of catalytic materials:
1. Thermal Stability: High temperatures can cause sintering, where particles agglomerate, leading to a loss of surface area and active sites. 2. Chemical Stability: Exposure to reactive chemicals may lead to oxidation, reduction, or leaching of active components. 3. Mechanical Stability: Physical wear and tear from operational conditions such as high pressure can degrade the catalyst structure. 4. Environmental Factors: Moisture, pH, and the presence of poisons (e.g., sulfur compounds) can adversely affect stability.
