Abstract :
A dendritic Pd-Cu electrode has been prepared by co-electrodeposition of palladium and copper with high cathodic over-potentials, in which hydrogen evolution occurred. The dendritic Pd-Cu was electrochemically de-alloyed to selectively remove copper. This de-alloyed Pd-(Cu) electrode has a dramatically increased surface-area that is appropriate for electrochemical sensor applications. Electrode characteristics for use as a non-enzymatic sensor were monitored by cyclic voltammetry and amperometry, in which detection signals for hydrogen peroxide (H2O2) were precisely measured. The prepared dendritic Pd-( Cu) electrode demonstrated outstanding electrocatalytic activity for H2O2 reduction with a detection limit of 1.78 x 10(-8) M, a wide dynamic range of 50 mu M to 10 mM, and high sensitivity of 915.25 mu A cm(-2) mM(-1).
