AI Technical Summary
Existing cobalt-based catalysts, such as CoS catalysts, suffer from poor stability and are easily oxidized, while CoO catalysts have poor conductivity and low catalytic efficiency, making it difficult to efficiently generate 1O2 for sterilization and pollutant degradation.
Oxygen-containing cobalt sulfide (CoSOX/HOPG) was deposited in one step on the surface of highly oriented pyrolytic graphite (HOPG) using chemical vapor deposition to form a polyhedral electrode. Combined with the CoSOX/HOPG electrode, 1O2 was efficiently generated under electrochemical conditions.
The CoSOX/HOPG electrode achieves efficient and stable generation of 1O2 in water treatment, rapidly inactivating bacteria and degrading dye pollutants. It has excellent bactericidal and degradation efficiency and is suitable for long-term use in complex environments.
