Abstract
- Two novel water-insoluble six-coordinated complexes, catena-(N,N-pyridine or imidazole)-μ<subscript>2</subscript>-oxalato iron(II) ((C<subscript>24</subscript>H<subscript>20</subscript>Fe<subscript>2</subscript>N<subscript>4</subscript>O<subscript>8</subscript>)<subscript>n</subscript> and (C<subscript>32</subscript>H<subscript>32</subscript>Fe<subscript>4</subscript>N<subscript>16</subscript>O<subscript>16</subscript>)<subscript>n</subscript> ⋅ C<subscript>2</subscript>H<subscript>5</subscript>OH, abbreviations: CPOFe or CIOFe, general term: COFe) have been prepared and characterized using single crystal X-ray diffraction, IR spectroscopy, element analysis, and UV-Vis spectroscopy. To investigate the catalytic properties, a simulated environment has been established. Methyl orange (MO) and Rhodamine B (RhB) have been chosen as model pollutants to characterize the photocatalytic system with hydrogen peroxide (H<subscript>2</subscript>O<subscript>2</subscript>) under visible light (λ ≥ 420 nm). The results indicate that COFe could effectively activate H<subscript>2</subscript>O<subscript>2</subscript> to oxidize and mineralize the substrates in aqueous media under ambient conditions, e.g. temperature, pressure, and visible light irradiation. The degradation rate of RhB has been over 98% in an hour. [ABSTRACT FROM AUTHOR]
