| 英文摘要 | 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 Fe-0-FeyCz/Fe-x, graphited ZIF-8, and rGO air-saturated aqueous suspension without additional energy. In this process, a strong Fe-pi interaction occurs on the composite surface, causing the surface potential energy similar to 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 O-2 in aqueous suspension, producing (OH)-O-center dot, H, and adsorbed organic cation radicals, which are hydrolyzed or hydrogenated to intermediate. The target pollutants undergo surface cleavage and convert H2O to (OH)-O-center dot, consuming chemical adsorption energy (similar to 2.852-9.793 kJ/mol), much lower than that of AOPs. Our findings provide a novel technology for water purification and bring new insights into pollutant oxidation chemistry. |
