Abstract :I n this work, platinum insert ignore into journalissuearticles values(Pt);, titanium insert ignore into journalissuearticles values(Ti); and silver insert ignore into journalissuearticles values(Ag); doped graphene oxide insert ignore into journalissuearticles values(GO); nanostructures were synthesized by using sonochemical technique, a relatively new technique in nanomaterial synthesis, and characterized in detail. The synthesized nanomaterials were characterized utilizing transmission electron microscopy insert ignore into journalissuearticles values(TEM); and X-ray photoelectron spectroscopy insert ignore into journalissuearticles values(XPS);. TEM images and XPS spectras showed that the dopping process was successful. In addition, a multilayer graphene oxide-silver nanoparticles insert ignore into journalissuearticles values(M-GOAgNPs); nano-structure was synthesized in this study for the first time, and it’s electrochemical performance was compared with GO-AgNPs. As a result of electrochemical study, the rate constants of the GO-AgNPs and M-GO-AgNPs modified electrodes were found as ksanodic= 6.62 s-1 and ksanodic= 6.78 s-1, respectively. Finally, the M-GO-AgNPs nano-structure obtained by sonochemical technique, a green chemistry synthesis technique, has been found to be suitable for use as an electrochemical sensor matrix.
