Abstract: In this study, Pd and PdAu catalysts were synthesized by NaBH4 reduction method and the activity of these catalysts for H2O2 reduction has been measured by cyclic voltammetry (CV) and chronoamperometry (CA) techniques. Electrochemical sensitivities of these CNT supported different atomic ratio PdAu bimetallic nanocatalysts were determined in 0.1 M pH 7.4 phosphate buffer solution towards H2O2.
