Photocatalytic degradation of toluene over spindle-like porphyrinoid nanostructures

摘要

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.
