A Printed Electrocatalyst for Hydrogen Peroxide Reduction

Gonzalez-Macia, Laura; Smyth, Malcolm R.; Killard, Anthony

Abstract

The modification of silver screen-printed electrodes with a dodecyl benzenesulfonic acid and KCl solution was performed by inkjet printing. Scanning Electron Microscopy was performed to characterize the electrode surfaces. Electrochemical reduction of H 2O 2 was studied and compared to electrodes modified by dip-coating. Analytical parameters of the all-printed electrode such as LOD, sensitivity and inter-electrode reproducibility were calculated (5.8×10 -6M, 4.9×10 -2AM -1cm -2 and approx. 10%) and contrasted with other data in the literature for the measurement of H 2O 2. Ink jet printing led to reductions in required surface modification times and improved signal to background levels and reproducibility. © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
