Yes, surface roughness can be controlled through various methods:
1. Surface Treatments: Techniques such as etching, polishing, and coating can be used to modify the surface roughness of a catalyst.
2. Material Synthesis: The synthesis conditions, such as temperature, pressure, and precursor concentration, can be adjusted to control the surface roughness of the resulting catalysts.
3. Post-synthesis Modifications: Techniques like thermal annealing or chemical treatments can be applied after the initial synthesis to further refine the surface roughness.
