A 5 wt% Pt/C catalyst with around 20 nm cubic
platinum particles was prepared through a conventional preparation
method (i.e., precursor impregnation, reduction, and calcination)
by choosing to use hydrophobic solvent in the impregnation procedure.
The precise nanoparticles shape control can be achieved by using
this preparation method as compared to the commonly used precolloid method.
These 20 nm cubic Pt particles showed high selectivity (ca. 99.4%)
for the hydrogenation of o-chloronitrobenzene.
platinum nanoparticles - shape control - supported
catalyst - hydrogenation - chloronitrobenzene
