High energy consumption is impedimental for eliminating refractory organic pollutants in water by applying advanced oxidation processes (AOPs). Herein, we develop a novel process destructing these organics chemical conjuncted Fe0-FeyCz/Fex, graphited ZIF-8, and rGO air-saturated aqueous suspension without additional energy. In this process, strong Fe-π interaction occurs on the composite surface, causing surface potential ∼310.97 to 663.96 kJ/mol. The electrons adsorbed group of are found delocalize around iron species could be trapped O2 suspension, producing ⋅OH, H, cation radicals, which hydrolyzed or hydrogenated intermediate. target undergo cleavage convert H2O consuming adsorption (∼2.852–9.793 kJ/mol), much lower than that AOPs. Our findings provide technology purification bring new insights into pollutant chemistry.
