Metal doped multiwalled carbon nanotube with metal oxide has unique properties which provide the remarkable studies in the field many applications. Zinc oxide nanoparticles (ZnO NPs) is a semiconducting material with a large excitation binding energy of 60 meV and wide energy band gap of 3.367 eV. The doping of silver naoparticle with ZnO/MWCNT composite materials offer values and makes it as advanced multifunctional materials. Silver nanoparticles are a highly active antibacterial agent for various types of microorganism and act as good photo degradation agent. In this work, the Ag doped ZnO/MWCNT nanocomposite have been synthesized by simplified spray pyrolysis method. Structural and morphological studies were carried out for the nanocomposite using Powder X-Ray Diffraction (PXRD), Field Emission Scanning Electron Microscope (FESEM). Elemental composition analysis was observed with Energy Dispersive X-ray (EDX) spectroscopy. Optical studies such as Ultra-Violet-visible and Fourier Transform Infra-Red (FTIR) Spectroscopy Uv-Vis and FTIR were employed to obtain the details of absorption and functional groups. The result obtained by antibacterial and photocatalytic on Ag:ZnO/MWCNT nanocompsite shows the expected inhibition for minimum quantities of product solution in µl and photodegradation with short duration respectively. 


Keywords: Nanocomposites, XRD, FESEM, Antimicrobial and Photocatalytic.
