Selective hydrogenation of nitrobenzene by thorny Pd NPs

we have developed a simple and environmentally benign one-step liquid-phase reduction method at ambient temperature, modulated by the ionic liquid [C4mim]Cl, for the synthesis of palladium nanoparticles (Pd NPs) with a unique "thorny" morphology. In terms of performance, the as-prepared thorny Pd NPs exhibit outstanding comprehensive catalytic properties in the hydrogenation of nitrobenzene.
