Yes, wettability can be engineered to optimize catalytic performance. Techniques include: 1. Surface Treatment: Modifying the surface of catalysts through chemical treatments or coatings to alter their hydrophilic or hydrophobic properties. 2. Nanostructuring: Creating nanostructures on the catalyst surface can enhance wettability by increasing surface roughness. 3. Functionalization: Adding functional groups that can interact favorably with the reactants can improve wettability.
