MnFe-PBA-derived porous catalysts with enhanced peroxymonosulfate activation for tetracycline removal: insights from experiment and theory

Abstract

*MnFe-PBAs have good degradation activity for TC, good stability and pH adaptability. The active sites composed of Fe₃O₄ and MnFe₂O₄ produce reactive oxygen through the redox cycle of metal valence. DFT calculations confirmed that MnFe₂O₄ has excellent electron transfer ability and identified Mn as the main active site.
