Mechanistic study on the photocatalytic degradation of rhodamine B <i>via</i> Mn-Schiff-base-modified Keggin-type polyoxometalate composite materials.

ABSTRACT: Organic-inorganic hybrid materials have significant potential in the photocatalytic degradation of Rhodamine B (RhB). In this study, five hybrid materials were successfully synthesized by modifying silicotungstic acid (H₄SiW₁₂O₄₀, abbreviated SiW₁₂O₄₀) with diverse MnL [L = Salen(L¹), 5-Br-Salen(L²), 5-Cl-Salen(L³), 3-Me-Salen(L⁴), di-tBu-Salen(L⁵)] complexes, specifically derivatives featuring various substituents. All the compounds are characterized by IR spectra, elemental analyses and thermogravimetric analyses (TGA). The band gaps of 1.33-1.52 eV and energy bands are obtained through the measurement of UV-Vis DRS and Mott-Schottky. Photocatalytic experiments of (MnL
