Abstract

Silver nanoparticles decorated on nanotubes morphology of Bismuth doped manganese oxide (Bi-MnOx) was prepared by Triton-X-100 polymer assisted precipitation process. In the second step, Ag nanoparticle with very fine particle size and graphene nanoparticle deposition by high power ultra-sonication method. Biogenic route synthesized silver nanoparticles have forms the spherical particle morphology with particle size obtained <10 nm. Polymer assisted method prepared pristine Bi-MnOx has existing in Nano- tubular morphology. The nanotube formation/nano particle incorporation has clearly confirmed by Scanning and Transmision electron microgph images. The synthesized silver nanoparticle modified Bi-MnOx composite was further tested for non-enzymatic detection of hydrogen peroxide sensor application. To exploit the biological activity of as prepared Bi-MnOx and biogenic route prepared silver quantum dot (QDs) particle and graphene oxide (GO) modified Bi-MnOx nanocomposite was further studied for gram positive and gram-negative bacterial strain. The nanoparticle dispersed Bi-MnOx could be adopted as low cost coating materials in health care smart building construction. Diffuse reflectance spectral studies are described for as prepared Ag QDs/GO doped Bi-MnOx is shown reduced band gap values (2.93 eV) than the pristine Bi-MnOx (3.17 eV) and it could be adopted for visible light photo-catalysis and antimicrobial applications.
