Cation-π induced surface cleavage of organic pollutants with ^⋅OH formation from H₂O for water treatment.

ABSTRACT: High energy consumption is impedimental for eliminating refractory organic pollutants in water by applying advanced oxidation processes (AOPs). Herein, we develop a novel process for destructing these organics in chemical conjuncted Fe⁰-Fe_yC_z/Fe_x, graphited ZIF-8, and rGO air-saturated aqueous suspension without additional energy. In this process, a strong Fe-π interaction occurs on the composite surface, causing the surface potential energy ∼310.97 to 663.96 kJ/mol. The electrons for the adsorbed group of pollutants are found to delocalize to around the iron species and could be trapped by O₂ in aqueous suspension_, producing ^⋅OH, H, and adsorbed organic cation radicals, which are hydrolyzed or hydrogenated to int
