Preparation of Mn₂O₃/MIL-100(Fe) composite and its mechanism for enhancing the photocatalytic removal of rhodamine B in water

Abstract

Effective charge transfer enhances the persulfate activation of Mn2O3/MIL-100(Fe) for photocatalytic removal of RhB under LED-generated visible light.

MIL-100(Fe)-Hybridized Nanofibers for Adsorption and Visible Light Photocatalytic Degradation of Water Pollutants: Experimental and DFT Approach

“…The FT-IR spectra (Figure S3) and XRD peaks (Figure f) indicate the presence of MIL-100­(Fe) crystals on the MIL-100­(Fe)@PAN web. MIL-100­(Fe) powders and the MIL-100­(Fe)@PAN membrane showed characteristic peaks at 3.4, 3.9, 6.3, 10.2, and 11° corresponding to (220), (311), (333), (842), and (422) planes of the MIL-100­(Fe). − …”

Interfacial synthesis of polyaniline–polypyrrole on electrospun vanadium oxide-embedded TiO2 nanofibers with enhanced photocatalytic performance

“…Nowadays, ∼20% of industrial dyes are discharged into the environment, causing serious environmental pollution and posing a threat to human health. 1,2 Among many technologies for dye removal and treatment, advanced oxidation processes (AOPs) are attracting attention due to their high versatility and efficiency, 3–11 thanks to the powerful oxidizing ability of free radicals, particularly sulfate radicals (SO 4 ˙ − ) generated from peroxymonosulfate (PMS). 4,7,10 Prior to use, PMS needs to be activated by an activating agent (catalyst) which undergoes redox cycles and catalyzes the formation of SO 4 ˙ − .…”

“…4,7,10 Prior to use, PMS needs to be activated by an activating agent (catalyst) which undergoes redox cycles and catalyzes the formation of SO 4 À . 5,6 In recent years, there has been considerable interest in the photocatalytic activation of PMS with the most-studied photocatalyst being TiO 2 due to its outstanding properties such as high chemical stability and environmental friendliness. [12][13][14][15] However, the wide bandgap energy (3.0-3.2 eV) and fast photogenerated electron-hole recombination of TiO 2 limit its use in the ultraviolet (UV) region (l r 388 nm) and lessen its efficacy in practical applications.…”
