In Situ Utilization of Co-Existing Metal Ions to Fabricate Single-Atom Catalyst for Boosting Fenton-Like Activity.

ABSTRACT: Heavy metals and organic pollutants commonly co-exist in the industrial wastewaters, and traditional treatment processes always treat them separately. Heavy metals can be effective active sites in heterogeneous Fenton-like catalysts, and their potential for in situ utilization and enhancement for organic pollutant degradation is promising but still underexplored. Herein, the metal-free TQBQ-COF is employed with abundant pre-designed metal-2N anchoring sites for the in situ capture of Cu²⁺ ions for boosting organic pollutant degradation. The co-existing Cu²⁺ can be successfully utilized to in situ fabricate a novel single-atom catalyst (SAC) within 1 min. The coordinated Cu significantly enhances visible-light absorption and charge separation ability, thereby substanti
