Oxidised Pd(II) complex species also present as dissolved species in the nanoparticle dispersion play no part in the exchange. We have studied the effects of several different variables on the rate of the selective H–D exchange activity for a model pyridine, i.e. 4-dimethylaminopyridine (DMAP). These variables include temperature, nanoparticle aging, nanoparticle re-reduction with H2 and nanoparticle immobilisation onto multi-walled carbon nanotubes (MWCNTs). We have also extended the study to related pyridine containing molecules.||Type of material:||Journal Article||Publisher:||Elsevier||Journal:||Catalysis Today||Volume:||139||Issue:||3||Start page:||154||End page:||160||Copyright (published version):||2008 Elsevier B.V.||Keywords:||Selective H–D exchange; Pd nanoparticles; Carbon nanotubes||DOI:||10.1016/j.cattod.2008.03.031||Language:||en||Status of Item:||Peer reviewed|
