Abstract

The antisolvent crystallization-based method, which involves forming precursor metal salt nanoparticles and converting

them to metal/oxide nanoparticles by reduction/oxidation can be used to synthesize nanocomposites composed of catalyst

nanoparticles and supporting materials. In this study, IrPt/Fe 2 O 3 nanocomposites comprising an IrPt catalyst and magnetic

Fe 2 O 3 supporter with a controllable Ir/Pt ratio are synthesized using a two-step antisolvent crystallization-based method.

The as-prepared nanocomposites exhibit excellent catalytic performance and reusability utilizing magnetism toward the

hydrogenation of p-nitrophenol (p-NP) .
