Description Carbon fiber microelectrodes coated with a silver and Nafion layers constitute sensitive H2O2 sensors. The silver at the electrode is composed of porous, partially aggregated and crystalline deposits of silver nanoparticles. A wide concentration range (from 1x10–5 up to 0.1 M H2O2) is achieved when using amperometry in stirred solution at 0 mV (vs. Ag/AgCl).
