Layered material gamma-ZrP supported platinum catalyst for liquid-phase reaction: a highly active and selective catalyst for hydrogenation of the nitro group in para-chloronitrobenzene.

Chemoselective hydrogenation of para-chloronitrobenzene without any dechlorination over Pt/gamma-ZrP catalyst proceeds effectively, which provides a clean and convenient approach to produce useful para-chloroaniline with excellent activity and selectivity.
