Biosynthesis Of Co3o4-Zno Nanocomposite Material Using Waste Extract Of Potato And Banana Fruits Peel For Antibacterial Application

Abstract

In This Study We Have Synthesized Co3o4, Zno Nps And Co3o4-Zno Nanocomposites Through Biological Method Using Cobalt Nitrate Hexahydrate And Zinc Acetate Dihydrate As A Precursor Material Using Waste Extract Of Potato And Banana Fruits Peel As A Capping Agent. The Synthesized Nps And Nanocomposites Were Characterized By Thermogravimetric Analysis (Tga/Dta), X-Ray Diffraction (Xrd), Scanning Electron Microscope (Sem), Uv?��?Vis Diffuse Reflectance Spectroscopy (Uv-Drs) And Fourier Transform Infrared (Ftir) Spectroscopy. The Optimized Crystal Size Of The Synthesized Nanocomposite Was Found To Be 13.54nm 30.02nm, And 9.39nm For Biologically Synthesized Co3o4 , Zno Nanoparticles And Co3o4-Zno Nanocomposite Using Extract Of Potato Fruit Peel, Respectively. The Crystal Size Of The Synthesized Nanocomposite Using Extract Of Banana Fruit Peel Was Also Found To Be 10.70, 12.79 And 9.52nm For Biologically Synthesized Co3o4, Zno Nps And Co3o4-Zno Nanocomposite, Respectively. The Bandgap For Synthesized Co3o, Zno Nps And Co3 O4-Zno Nanocomposite Using Peel Of Potato Were 3.25, 3.08 And 3.33 Ev, Respectively. The Bandgap For Synthesized Co3o4,, Zno Nps And Co3o4-Zno Nanocomposite Using Peel Of Banana Were 3.60, 3.17 And3.56 Ev, Respectively. The Xrd Pattern With Sharp Peaks Describes The Crystalline And Purity Of Co3o4, Zno Nps And Co3o4-Zno Nanocomposite. The Morphology Of Co3o4, Zno Nanoparticles And Co3o4-
