How do Hydrophobic Coatings Enhance Catalytic Activities?
Hydrophobic coatings can enhance catalytic activities through several mechanisms:
1. Selective Adsorption: By repelling water, hydrophobic coatings can promote the adsorption of non-polar reactants, thereby increasing their concentration on the catalyst surface.
2. Stability Improvement: In aqueous environments, hydrophobic coatings can protect the catalyst from deactivation due to hydration or leaching of active components.
3. Mass Transfer Enhancement: These coatings can reduce the formation of water layers that hinder the diffusion of reactants to the active sites, thereby improving mass transfer.
