Enhanced photocatalytic activity and magnetic properties of CNTs/Sn-doped Co3O4 nanocomposite

Photocatalysis is a green technology which transforms available photon energy into useful chemical energy. The reaction mechanism based on the ability to create electron–hole pairs under appropriate light. Semiconductors have attracted great attention in photocatalysts because of their high photosensitivity. Spinel–type cobalt oxide nanorods been prepared by simple hydrothermal method using nitrate as precursor. Sn-doped Co3O4 was composited with carbon nanotubes for better photocatalytic activity. An extensive characterization samples carried out X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), dispersive spectroscopy (EDS), Fourier transform infrared (FTIR), Vibrating sample magnetometer (VSM) and UV–Visible absorption spectroscopy. XRD results show formation phase FCC structure, FESEM confirms morphology VSM taken at room temperature shows an antiferromagnetic behavior. investigation activity done methyl orange dye. At end, responsible CNT/Sn–CO discussed.
