Surfactant-free synthesis of reduced graphene oxide supported porous PtAu alloyed nanoflowers with improved catalytic activity

Abstract

A simple, facile one-pot wet-chemical co-reduction method was developed for synthesis of porous PtAu-nanoflowers/rGO with the assistance of <italic>p</italic>-aminopyridine. The as-prepared nanocomposites displayed excellent catalytic activity for 4-nitrophenol reduction.
