(A) Adsorption of different dyes on the surface of MnTNPP/SAPy@TiO2 at pH = 3 (RhB: rhodamine B, CV: crystal violet, MB: methylene blue, MR: methyl red, MO: methyl orange); (B) Photocatalytic degradation of RhB dye under irradiation of various light sources in the presence of MnTNPP/SAPy@TiO2 (UVC, UVA, CFL, Blue LED, , Reptile) and (C) in the presence various catalyst under CFL light; (D) Time course photodegradation of RhB under CFL light in the presence of MnTNPP/SAPy@TiO2 and inset represents pseudo-first-order kinetic. The reactions were run three times using a 50 ml aqueous solution with pH = 3 containing 2 ppm RhB, 5 mg (A, B, C) and 10 mg (D) catalyst and 62 µl H2O2 at 298 K.
