dc.description.abstract | The development of highly active porous catalysts is crucial for the efficient catalytic oxidation of organic pollutants. In this study, we synthesized a manganese–iron bimetallic catalyst supported on iron foam (MnFe-IF) using a dual chloride aqueous corrosion method to enhance potassium periodate (PI) activation. The unique morphology and synergistic effects of MnFe-IF led to exceptional activity and durability in degrading various organic pollutants, surpassing conventional non-precious metals and previously reported porous catalysts. Electrochemical evaluations, scavenging tests, and electron spin resonance analysis reveal that an electron transfer mechanism drives organic removal in the MnFe-IF/PI system. The catalyst activates PI, generating high-potential intermediates that significantly enhance pollutant degradation. Additionally, the transformation of Fe(II)/Fe(III) and Mn(II)/Mn(III)/Mn(IV) promotes the cooperative roles of singlet oxygen and superoxide radicals in organic elimination. This work provides new insights into the synthesis of effective porous catalysts for oxidizing organic contaminants. | |
