Bimetallic Pd–Cu nanocrystals and their tunable catalytic properties†
Abstract
Monodisperse Pd–Cu bimetallic nanocrystals (NCs) with tunable compositions (Pd0.2Cu0.8, Pd0.3Cu0.7, Pd0.5Cu0.5, Pd0.7Cu0.3, Pd0.8Cu0.2) and controlled sizes (5.2 nm, 6.8 nm, 8.1 nm, 16.4 nm, 19.9 nm) were easily obtained in an octadecylamine (ODA) synthetic system, which exhibited tunable catalytic properties for styrene epoxidation and ethanol electro-oxidation.
