摘要

The present study reports the synthesis of hybrid system of polypyrrole (PPy) conducting polymer and silicon nanowires (SiNWs) for photo-catalytic application. This hybrid structure (PPy /SiNWs) was characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), ultraviolet–visible absorption (UV–Vis), and carrier lifetime measurements. The surface and transversal imaging justifies the formation of SiNWs and exhibits a spherical granular morphology of the grown PPy thin film. FTIR and EDX study confirms the synthesis of PPy. The XRD pattern reveals the amorphous nature of the grown PPy thin film. The photo-catalytic properties of the PPy /SiNWs structure were evaluated by the photo-degradation of Amido Black 10B solution, which exhibits the maximum photo-degradation efficiency of 70.95% after 90 min of visible light illumination.
