Silver Nanoparticles And Defect-Induced Visible Light Photocatalytic And Photoelectrochemical Performance Of Ag@M-Tio2 Nanocomposite, Mohammad Mansoob Khan Dr, S. A. Ansari, M. O. Ansari, M. H. Cho
Dr. Mohammad Mansoob Khan
An electrochemically active biofilm-assisted visible light active Ag@m-TiO2 photocatalyst was fabricated. The resulting nanocomposite was characterized by X-ray diffraction, transmission electron microscopy, diffuse absorbance/reflectance spectroscopy, photoluminescence spectroscopy, and X-ray photoelectron spectroscopy. The photocatalyst showed high photocatalytic activity and photoelectrochemical behavior due to the synergistic effect of the surface plasmon resonance (SPR) of Ag nanoparticles (AgNPs) and the induced defects in TiO2 (m-TiO2) nanoparticles. Ag@m-TiO2 nanocomposite showed much higher light harvesting ability because of the reduced band gap of m-TiO2 as well as the SPR characteristics of the AgNPs. The visible light photocatalytic experiments showed that the Ag@m-TiO2 nanocomposite possessed excellent …
