Effective removal of tetracycline hydrochloride over Cu-doped carbon nitride via an adsorption-promoted Fenton-like catalysis

A Cu-doped carbon nitride bifunctional material (Cu/CN) synthesized by thermal polymerization exhibits remarkably enhanced TCH adsorption and degradation performance by the synergistic effect between electron-enriched CN and the Cu ⁺ /Cu ²⁺ redox cycle.
