“…Also, MOFs have the advantages of uniform shape and size, porous, diverse, and tunable surfaces . For instance, CPM-5 (crystalline porous materials) has been used as a sulfur fixative for Li–S batteries, zinc–air batteries, and as an H 2 separation membrane. − However, MOFs have poor electrical conductivity and low mass permeability . At present, most researchers choose carbon as the support material of the catalyst, such as carbon nanotubes, carbon nanofibers, carbon black, and so on. , Reduced graphene oxide (rGO) has the advantages of good stability, corrosion resistance, conductivity, and a large surface area, which can promote electron transmission, increase the contact area of reactants, and thus improve catalytic efficiency .…”
