Resins function as catalysts by providing an active surface where reactants can adsorb and react. The functional groups on the resin facilitate the conversion of reactants to products. For example, in ion-exchange resins, the ionic groups interact with reactants, making it easier for chemical transformations to occur. Similarly, in polymer-supported metal catalysts, the metal particles are finely dispersed on the resin surface, maximizing exposure to reactants and enhancing reaction rates.
