Synthesis and characterization of low- cost silicon nanowires supported Ag nanoparticles from silicon powder and their photo-catalytic activity for degradation of Rhodamine B

The low-cost silver modified silicon nanowires obtained from siliconpowder for photo-catalytic application with longer stability and simple synthetic method were prepared. X-ray diffraction (XRD) and scanning electron microscopy (SEM)used to detect the crystalline structure and diameter of the nanowires. The photo-catalytic activitywas estimated by the degradation ofRhodamine B under visible light.
