文摘
- •
It was studied the synthesis of palladium nanoparticles by reduction of Pd (acac)2 with ethylene glycol over carbon nanotubes and graphite oxide.
- •
Well-dispersed metallic palladium nanoparticles of similar average size were obtained over Pd/CNTEG and Pd/GOEG.
- •
The morphology and surface chemistry do not seem to affect the size of the nanoparticles obtained by this methodology.
- •
Pd/CNTEG and Pd/GOEG were studied on the para-chloronitrobenzene hydrogenation and compared with catalysts prepared by impregnation.
- •
The catalysts Pd/CNTEG and Pd/GOEG were more active than the catalysts prepared by impregnation and they could be reused on successive cycles.
