Persistent organic contaminants in water pose imminent threats to aquatic ecosystems and human health, yet conventional treatment systems are not able remove them effectively. Electrochemical oxidation is a promising alternative for the mineralization of persistent compounds. Herein, novel hierarchical porous PbO 2 electrode fabricated via direct electrodeposition on templated fluorine‐doped tin oxide surface. Physical electrochemical characterization confirm superior properties (e.g., enhanced active surface areas) produced electrode. In addition, compared with macroporous films, shows significantly improved degradation performance against variety pollutants, including sodium dodecyl sulfate, rhodamine B, diclofenac. Overall, it demonstrated that can be utilized efficient contaminants.
