Abstract

Platinum nanoparticles supported on porous silicon were synthesized by radiation-chemical reduction in solutions of reverse micelles. The Pt nanoparticles obtained are electrondeficient. The degree of porosity, conductivity type, pore geometry of the silicon matrix, and precursor parameters affect the size, shape, and charge state of the platinum catalysts.
