How Does Surface Roughness Influence Catalyst Deactivation?
Surface roughness can influence catalyst deactivation in several ways:
1. Fouling: Rough surfaces may be more prone to fouling due to the accumulation of reaction by-products in the valleys, which can block active sites.
2. Sintering: High surface roughness can lead to increased sintering, where particles agglomerate and lose their active surface area, reducing catalytic activity.
3. Corrosion: Rough surfaces may also be more susceptible to corrosion, particularly in harsh reaction environments, leading to catalyst degradation.
