To reduce the energy input needed for Faradaic water treatment, catalysts have been introduced to mitigate the substantial deviation (e.g., overpotential) from thermodynamics. These catalysts enhance surface affinity, strengthen adsorption, and reduce the activation barrier of target redox reactions; they can also help control side reactions and the final products of the electrochemical process. For example, electrocatalysis can facilitate H2O2 generation as an aquatic disinfectant as well as the transformation of selenate to elemental selenium (e.g., for resource recovery) instead of producing toxic hydrogen selenide . Catalysts are also used to selectively control overpotentials, enabling the redox transformation of recalcitrant aquatic pollutants that surpass the typical electrochemical window of water . For instance, electrooxidation of per-and polyfluorinated alkyl substances (PFAS) can be significantly enhanced by pairing electrodes with high oxygen evolution overpotentials (such as boron-doped diamond, Ti4O7, SnO2, and PbO2 ) with catalysts that facilitate PFAS oxidation.
