PSMNPs offer several advantages: - Stability: The polymer matrix prevents agglomeration of metal nanoparticles. - Reusability: These catalysts can often be recovered and reused without significant loss of activity. - Tunability: The physical and chemical properties of the polymer can be tailored, allowing for the fine-tuning of catalytic activity. - Functionalization: Polymers can be modified with functional groups that enhance the interaction between the catalyst and reactants.
