Abstract

Pt/CeO₂ hybrid nanostructures consisting of sub-3 nm Pt nanocrystals supported on octahedral CeO₂ nanocrystals can be synthesized by in situ reduction of a Pt precursor in the presence of CeO ₂ octahedra. Pt/CeO₂ hybrid nanostructures exhibit higher resistance to poisoning by the reaction product during the catalytic reduction of p-nitrophenol into p-aminophenol by NaBH₄ as compared to the unsupported Pt nanocrystals.
