Anions can impact catalytic reactions in several ways:
Charge Balance: Anions help in maintaining the overall charge balance of catalytic complexes, which is essential for catalytic activity. Electronic Effects: Anions can affect the electronic properties of metal centers, influencing their reactivity and selectivity. Structural Effects: In heterogeneous catalysis, anions can alter the surface structure of catalysts, affecting the adsorption and desorption of reactants and products.
