The Manganese complex of meso-tetrakis (4-carboxyphenyl) porphyrin was immobilized onto the surface of functionalized activated carbon and used as a heterogeneous catalyst for the oxidation of different alkenes. The heterogenized catalyst has been fully characterized using Ultraviolet–visible (UV-Vis), Fourier-transform infrared (FTIR), and atomic absorption spectroscopies as well as thermogravimetric analysis (TGA), scanning electron microscopy (SEM), and […]
