Özet

In this study, Pd nanoparticles-graphene (Pd-G) nanocomposites were fabricated on the surface of a nickel foam electrode using a simultaneous electrochemical co-deposition method. For this purpose, the electrochemical deposition occurred by applying a constant potential from the solution containing Pd2+ ions and graphite oxide under stirring conditions. This method is cheap, easy, and allows direct deposition of the nanostructures on the electrode surface in a single step. The structural and morphological characterizations of electrochemically fabricated Pd-G nanocomposites were performed by XRD, XPS, SEM, and EDS techniques. The composite electrode was tested in non-enzymatic glucose sensing as a biosensor application. The electrocatalytic activity of Pd-G was investigated by cyclic voltammetry (CV). The detection limit and sensitivity were calculated as 0.081 mu M (S/N = 3) and 6868.6 mu A cm-2 mM-1 by using amperometry.
