Abstract
Proposed is a single-atom catalyst (SAC) including a nitrogen-doped carbon structure and a single-atom metal, wherein the single-atom metal forms a coordination bond with a nitrogen atom of the nitrogen-doped carbon structure. When using an electrochemical cell having a pair of electrodes including the single-atom catalyst in an electrochemical advanced oxidation process (EAOP) for water treatment, organic contaminants in wastewater are efficiently degradable under mild pH conditions.
