The scheme of coordination bridge modification provides a new vision for regulating the catalytic pathway, but how to change the surface coordination of peroxymonosulfate (PMS), thereby affecting the catalytic mechanism of PMS, is still an unknown field. In this, we found that MIL-101(Fe) is expected to control the surface catalytic pathway via the bidentate binuclear coordination configuration, thereby realizing the rapid oxidative detoxification of toxic organic pollutants and CO2 conversion. Introducing Cu on the surface of MIL-101(Fe) to change the surface chem. environment (MIL-101(Fe)/CuFeOx) can shift the catalytic pathway, thereby promoting a 14.5-fold improvement in Bisphenol A (BPA) oxidation kinetics (from 0.00697 min-1 to 0.101 min-1). Characterization, experiments, and d. functional theory (DFT) results show that Cu in the vicinity of Fe can tune the electronic structure and properties of Fe-O-Cu, thereby enhancing the electron transfer rate at the active center, facilitating electronic transitions and PMS adsorption. More importantly, shifting the binding configuration of PMS from monodentate mononuclear coordination on a single Fe center to bidentate binuclear coordination on Fe/Cu centers, shorter distance coordination structures and O-O pulling of PMS. The effect promoted PMS cleavage to generate more ROS and changed the catalytic pathway from the radical pathway to the 1O2 and high-valent metal species pathway. The free radical/non-radical pathway co-mediated by 1O2, high-valent metal species, ·OH and SO·-4 can effectively reduce the biotoxicity of toxic organic pollutants, and can utilize alkali environment captures CO2 as a stable carbonate for environmental use. This study provides a strategy for manipulating the catalytic pathway through coordination configuration and a feasible idea for CO2 conversion in wastewater treatment. The experimental part of the paper was very detailed, including the reaction process of Triacetonamine(cas: 826-36-8Synthetic Route of C9H17NO)
Triacetonamine(cas: 826-36-8) is a member of piperidine. Piperidine-containing compounds are also frequently employed in synthesis as ligands or auxiliaries. Accordingly, many efforts have been devoted to the development of novel methods for the synthesis of these compounds over the years.Synthetic Route of C9H17NO
