Synthesis of palladium nanoparticles Graphical abstractHighlights  The synthesis of palladium nanoparticles by reduction of the organometallic precursor Pd (acac)2 with ethylene glycol and their deposition over carbon nanotubes (CNT) and graphite oxide (GO) was studied. Well-dispersed metallic palladium nanoparticles of similar average size were obtained over Pd/CNTEG and Pd/GOEG, this suggesting that the morphology and surface chemistry do not affect the size of the nanoparticles obtained by this methodology  The catalytic performance of Pd/CNTEG and Pd/GOEG was studied on the parachloronitrobenzene chemoselective hydrogenation and compared with analogous catalysts prepared by traditional impregnation. The activity of Pd/CNTEG and Pd/GOEG was higher than that obtained with the catalysts prepared by impregnation and both catalysts could be reused on successive cycles.

A new method for incorporating polyethyleneimine (PEI) in algal beads: High stability as sorbent for palladium recovery and supported catalyst for nitrophenol hydrogenation

“…Dong et al [10] investigated the use of Au or Pd nanoparticles supported on magnetic porous carbon (MPC) composite for 4-nitrophenol reduction and their results show that the supported catalysts exhibited comparable or better catalytic activity than most of the reported catalysts. Palladium nanoparticles over graphite oxide and carbon nanotubes, reported by Dongil et al [11], present good reusability. These supported catalysts use green and economical support material and metals can be recycled and reused from various waste sources.…”

Tetraalkylammonium Functionalized Hydrochars as Efficient Supports for Palladium Nanocatalysts

“…mesoporous silica, zeolites, clays, polymers, metal‐organic frameworks or carbon‐based materials . Particularly concerning the latter materials, carbon nanospheres, nanotubes, halloysite‐hydrochar nanocomposites, and graphene oxide, are the most used.…”

Pt/Al2O3 coated with N-doped carbon as a highly selective and stable catalyst for catalytic hydrogenation of p-chloronitrobenzene to p-chloroaniline

“…For catalytic hydrogenation reduction, noble metals such as Pd and Pt are highly active because of their strong abilities for H 2 activation under mild conditions. 5,6 However, supported noble metal catalysts exhibited low selectivity because dechlorinated byproducts were inevitably formed due to their strong hydrodechlorination capabilities. 5,7 For example, supported Pt catalysts were considered as the most selective ones among supported noble metals for the catalytic conversion of CNBs to CANs, 3,8,9 however, Pt/C catalyst only displayed 75.2% selectivity to p-CAN at 100% conversion of p-CNB.…”
