The Development of High-Effective Composites based Porous Silicon with Platinum Nanoparticles for Autonomous Energy Sources
Platinum-porous silicon nanocomposites were synthesized by chemical reduction of ions in water-organic
solutions of reverse microemulsions. Physico-chemical characteristics of the nanocomposites were studied by atomic force
microscopy, X-ray phase analysis, cyclic voltammetry. It was found that the smallest platinum nanoparticles size is observed
when the water pool size ω is 5. Investigating of catalytic activity in the hydrogen oxidation and oxygen reduction reactions
showed the high catalytic activity.
