Abstract

The prospects for the formation of Fe–Pt nanoparticles in the pore structure of highly porous carbonizate of sapropelic coal are analyzed. Specific thermally stimulated behavior is established, demonstrating the great potential of such carbonizate to address the oxidation of iron often observed in the synthesis and storage of Fe–Pt nanoparticles, which are promising for catalytic and magnetic applications. In the Fe–Pt/C system, spontaneous reduction processes are noted at 250–900°C in an inert atmosphere. The reduction is due to CO and H2 formed by catalytic reactions involving the carbon matrix and a platinum-bearing metal phase.
