Huang, Zhiyan published the artcileDefect-rich carbon based bimetallic oxides with abundant oxygen vacancies as highly active catalysts for enhanced 4-aminobenzoic acid ethyl ester (ABEE) degradation toward peroxymonosulfate activation, Quality Control of 826-36-8, the publication is Chemical Engineering Journal (Amsterdam, Netherlands) (2020), 124936, database is CAplus.
meeting severe environmental problems, highly efficient, environment-friendly, multiple reusable catalysts are demanding to develop. this work prepared C-based bimetallic oxides with O vacancies for peroxymonosulfate activation to degrade 4-aminobenzoic acid Et ester (ABEE). among different molar ratios of Fe2+ and Mn ions, Fe1Mn1-Fe NC had the optimum catalytic performance. ABEE degradation should have free radical and non-free radical pathways. all sulfate, hydroxyl, and superoxide radicals and singlet oxygen were responsible for efficient ABEE degradation and mineralization. lattice O was the main reactive site for ABEE degradation electron transport provided a good synergistic redox reaction between Fe and Mn and promoted lattice O release. a proposed pathway for ABEE degradation included electrophilic and radical addition, H-abstraction reaction, and diazotization. this work was expected to provide rational design of bimetallic materials with oxygen vacancies for in-situ environmental remediation.
