Photocatalytic Degradation of Toluene Over Spindle-like Porphyrinoid Nanostructures

In this work, spindle-like Zn-TPyP sample was synthesized by a facile solution-phase method with CTAB as the surfactant. The Zn-TPyP particles with spindle shape showed photocatalytic activity. The structural properties of spindle-like Zn-TPyP sample were systematically investigated by X-ray powder diffraction (XRD), scanning electronic microscopy (SEM), transmission electronic microscopy (TEM), energy-dispersive X-ray spectra (EDS), X- ray photoelectron spectroscopy (XPS) and UV-Vis diffuse reflectance spectroscopy (DRS) techniques. The photocatalytic performance of the spindle-like Zn-TPyP sample was studied by degrading toluene under xenon lamp irradiation by in-situ FTIR spectroscopy. The results indicate that the spindle-like Zn-TPyP particles exhibited favorite photocatalytic degradation activity.
