The enhancement in catalytic activity by ionomers can be attributed to several factors:
Increased Surface Area: The ionic groups can help disperse catalytic particles more evenly, increasing the active surface area available for reactions. Stabilization of Active Sites: The ionic environment can stabilize metallic nanoparticles, preventing agglomeration and deactivation. Improved Mass Transport: The polymer matrix can facilitate the transport of reactants and products to and from the catalytic sites, enhancing the overall reaction rate.
