Several factors can contribute to adhesion problems in catalysis:
1. Surface Roughness: The physical texture of the substrate can influence how well a catalyst adheres. Rough or irregular surfaces can lead to weak bonding. 2. Chemical Compatibility: The chemical nature of both the catalyst and the substrate can affect adhesion. Incompatible materials may not bond effectively. 3. Thermal Expansion: Differences in the thermal expansion coefficients of the catalyst and substrate materials can cause stress at the interface, leading to detachment. 4. Environmental Conditions: Factors such as temperature, pressure, and the presence of reactive species can alter the adhesion properties over time.
