Several factors can impact the wettability of a catalyst surface: 1. Surface Roughness: Rough surfaces tend to increase contact area, which can enhance wettability. 2. Surface Chemistry: The presence of hydrophilic or hydrophobic groups on the catalyst surface can significantly alter wettability. 3. Temperature: Higher temperatures can reduce the viscosity of liquids, potentially improving wettability. 4. Pressure: Changes in pressure can alter the contact angle, thus affecting wettability.
