Novel recoverable biomimetic catalysts were prepared by the coordinative anchoring of an
iron (III) meso-tetraphenyl porphyrin complex [Fe (TPP) Cl] and some derivatives on the
activated multi-walled carbon nanotube (AMWCNT) via hydroxyl functionality (Fe-Por–
AMWCNT). The simple heterogeneous catalyst [Fe (TPP) Cl–MWCNT] was characterized by
powder X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron
microscopy (SEM), Raman, FT-IR and UV–vis spectroscopy. The amount of catalyst loading …

A Fe–porphyrin catalyst was anchored covalently onto functionalized multi-walled carbon
nanotubes. The heterogeneous catalyst was characterized by powder X-ray diffraction,
transmission electron microscopy, scanning electron microscopy, FTIR, UV-Vis spectroscopy
and thermogravimetric analysis (TGA). The catalyst loading on the nanotube support was
determined by atomic absorption spectroscopy (AAS). The aerobic oxidation of olefins and
sulfides under ambient conditions was efficiently enhanced under the influence of the …
