The strong metal-support interactions induced electrocatalytic three-electron oxygen reduction to hydroxyl radicals for water treatment.

ABSTRACT: As a promising environmental remediation technology, the electro-Fenton (EF) process is mainly limited by the two rate-limiting steps, which are H₂O₂ generation and activation. The electrocatalytic three-electron oxygen reduction reaction (3e^- ORR) can directly activate oxygen to hydroxyl radicals (•OH), which is expected to break through the rate-limiting steps of the EF process. However, limited success has been achieved in the design of 3e^- ORR electrocatalysts. Herein, we propose Cu/CoSe₂/C with the strong metal-support interactions to enhance the 3e^- ORR process, exhibiting remarkable reactivity and stability for •OH generation. Both experiment and DFT calculation results reveal that CoSe₂ is conducive to the
