摘要
MIL-88A(Fe)/BOHP (MxBy) heterojunctions were firstly fabricated via a ball-milling method, which were adopted as catalysts to activate hydrogen peroxide (H2O2) with the aid of visible light illumination to build a heterogeneous photocatalysis-Fenton-like synergetic system. The catalytic degradation efficiency of enrofloxacin (ENR) (10 mg/L) in the optimal M3B7/Vis/H2O2 system reached nearly 100 % with appreciable mineralization ability. Experimental and theoretical results co-unraveled that the formation of interfacial Fe−O−P chemical bonds between MIL-88A(Fe) and BOHP effectively reduced the charge transfer energy barrier (59.41–26.69 eV) and migration distance (3.104–1.917 Å), allowing the photo-generated carriers to be efficiently separated in space and improving the activation efficiency of H2O2 for producing more active species. Impressively, the constructed M3B7/Vis/H2O2 system was a cost-optimal and green technology for antibiotic wastewater treatment based on Electrical Energy per Order (EE/O) concept, life cycle assessment (LCA) and quantitative structure–activity relationship (QSAR) analysis.
