In situ electrogenerated Cu(III) triggers hydroxyl radical production on the Cu-Sb-SnO₂ electrode for highly efficient water decontamination.

ABSTRACT: The electrochemical oxidation process has the unique advantage of in-situ •OH generation for deep mineralization of organic pollutants, which is expected to provide a solution for the globally decentralized wastewater treatment and reuse. However, it is still a great challenge to develop low-cost anodes with ultrahigh •OH yield and low energy consumption. Here, a low-cost and stable mixed metal oxide (MMO) anode (Cu-Sb-SnO₂) developed by a simple and scalable preparation process presents extremely high organic pollutants degradation efficiency and low energy consumption. The tetracycline degradation kinetics constant of the Cu-Sb-SnO₂ system (0.362 min^-1) was 9 to 45 times higher than that of other prepared anodes, which is superior to the existing anodes r
