Popis | Carbon fiber microelectrodes equipped with nanostructured metals (platinum and silver) and covered with a Nafion layer constitute sensitive H2O2 sensors. Metallic layers on carbon fibers were prepared by surfactant assisted electrodeposition. In the case of silver, the procedure leads to coating which is composed of porous, partially aggregated and crystalline deposits containing silver nanoparticles. The electrodeposition of platinum leads to carbon fiber decorated with clusters of platinum nanoparticles. After coating the electrodes with protective and antiinterference barrier made of Nafion, the sensing properties of the prepared microelectrodes towards hydrogen peroxide are investigated. |
