Novel composite enhances photocatalytic degradation of pollutants in wastewater under visible light.
Novel β-(α-NaO)CoPc/TiO 2 -MIL-100 (Fe) composite was prepared via a impregnation method in this study. The prepared composite was characterized by Fourier transform infra-red (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), N 2 isothermal adsorption-desorption test. Compared with bare photocatalysts (i.e. TiO 2 and MIL-100 (Fe)), the composite exhibited enhanced photoactivity under visible light irradiation towards Crystal Violet (CV).The photocatalytic degradation studies found that almost 100 % of organic pollutants were decomposed within 120 min of visible light irradiation. The enhanced photocatalytic properties of the composite should be attributed to the improved adsorption ability which is beneficial to establish the rapid adsorption-desorption system and promote the efficient separation of the photogenerated electron-hole pairs. The photocatalytic performance and photocatalytic mechanism of ternary composites doped with metal oxides were mainly explored. In brief, the present study confirms the potential use of β-(α-NaO)CoPc/TiO 2 -MIL-100 (Fe) nanocomposite in the field of industrial applications to eliminate the organic pollutants from waste water.
