Electrode Materials Based on Porous Silicon with Platinum Nanoparticles for Chemical Current Sources

详细

Composites on porous silicon with platinum nanoparticles were prepared with the aim of developing structural materials for electrochemical power sources. The size and shape of the nanoparticles in the silicon matrix were examined by atomic force and high-resolution transmission electron microscopy. The catalytic activity of the nanomaterials in hydrogen oxidation and oxygen reduction was evaluated. The models based on the composite electrodes prepared were tested under the conditions of operation of hydrogen–air fuel cells.
