Özet

This study used the Chemical Bath Deposition method, which is quite simple and cheap, to produce GO/MoO3 nanocomposite, whose high capacitance properties draws attention. The Graphene oxide solution is prepared by synthesizing through the Hummer Method. These two materials were left to grow slowly on their own so that GO/MoO3 nanocomposite structures form thin films on Glass, Poly(methyl methacrylate), Fluorine tin oxide, and indium tin oxide substrates. The surface and structural properties of these GO/MoO3 nanocomposite structures were characterized by Scanning Electron Microscopy, Energy Dispersive X-ray, FTIR, X-ray diffraction, and Atomic Force Microscopy. The nanocomposites' capacitance properties produced on different substrates were measured in -0.2 - 0.2 V at different scan rates. As a result, the highest specific capacitance values were achieved at 25 mV/s scan rate, as 587 F/g, for Poly(methyl methacrylate).
