- Natural hydroxyapatite supported cobalt tetrasulfophthalocyanine (CoTSPc-NHAp) as a green, renewable and biomaterial-based heterogeneous catalyst that mediates oxidation of various secondary benzylic C–H bonds, secondary benzylic and primary and secondary aliphatic alcohols to their corresponding aldehydes and ketones in high yields and selectivity without any additional oxidizing reagent is reported. The structure of the synthesized catalyst was characterized by inductively coupled plasma-optical emission spectrometry (ICP-OES), Fourier transform infrared (FT-IR), X-ray diffraction (XRD), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), and the energy dispersive spectroscopy (EDS) analysis.
