Glucose sensitivity of platinum-based alloys incorporated in polypyrrole films at neutral media

The conducting polymer films with metal particles incorporated into the fil m by electrodeposition have excellent properties in regard to various elect rode reactions in fuel cell applications. This communication presents some new results concerning the electrooxidation of D-glucose at modified platin um electrodes dispersed in polypyrrole film in neutral media. The addition of lead, tin, bismuth, and ruthenium to platinum causes the modification of electrocatalytic behavior of the electrode. The modification of the electr ode surface is one means of minimizing poisoning effect, increasing the ele ctrode activity. This reaction has great deal of interest in view of its ap plications on detection systems (glucose sensor), fuel cells (pacemakers) a nd electroorganic synthesis. (C) 2001 Elsevier Science B.V.
