Electrocatalytic behavior of the PS-PB modified electrode. A) Effect of the loading of the PB particles on the PS beads on the amperometric response to 0.1 mM hydrogen peroxide. B) Cyclic voltammograms for 0.5 mM hydrogen peroxide at the PS-(a) and PS-PB (b) modified electrodes. C) Amperometric response to successive additions of 0.1 mM hydrogen peroxide at the unmodified (a) and PS-PB modified (b) gold electrodes. Operating potential (A), 0.0 V; scan rate (B), 50 mV/s. Electrolyte, 0.1 M KCl. Surface modification protocol. see Section 2.7.
