Abstract:
A 5% Pt/C catalyst with ~20 nm cubic platinum particles was prepared using a traditional preparation method (i.e. precursor impregnation, calcination, and reduction) and choosing a hydrophobic solvent in the impregnation procedure. These 20 nm cubic Pt particles showed 99.4 %selectivity for the hydrogenation of o-chloronitrobenzene (o-CAN) and 88.7% selectivity for reductive alkylation of aniline. We demonstrate that traditional preparation methods also can achieve precise nano-particle shape control as compared to the commonly used method of impregnating supports with a pre-prepared nano-particle colloid with already well defined particle morphology.
