Platinum and palladium on carbon nanotubes: Experimental and theoretical studies
MetadataShow full item record
Pristine and oxygen plasma functionalised carbon nanotubes (CNTs) were studied after the evaporation of Pt and Pd atoms. High resolution transmission electron microscopy shows the formation of metal nanoparticles at the CNT surface. Oxygen functional groups grafted by the plasma functionalization act as nucleation sites for metal nanoparticles. Analysis of the C1s core level spectra reveals that there is no covalent bonding between the Pt or Pd atoms and the CNT surface. Unlike other transition metals such as titanium and copper, neither Pd nor Pt show strong oxygen interaction or surface oxygen scavenging behaviour.

Catalytic partial oxidation of propylene to acrolein: the catalyst structure, reaction mechanisms and kineticsFansuri, Hamzah (2005)Bismuth molybdates have long been known as active catalysts for selective oxidation of olefins. There are several phases of bismuth molybdates but only three of them are known to be active for partial oxidation of propylene ...
Do terminally ill people who live alone miss out on home oxygen treatment? An hypothesis generating studyCurrow, D.; Christou, T.; Smith, J.; Carmody, S.; Lewin, Gill; Aoun, Samar; Abernethy, A. (2008)INTRODUCTION: Oxygen for refractory dyspnea at the end of life is commonly prescribed, even when the criteria for long-term home oxygen therapy are not met. Is palliative oxygen less likely to be prescribed when a person ...
Oxygen titration after resuscitation from out-of-hospital cardiac arrest: A multi-centre, randomised controlled pilot study (the EXACT pilot trial)Bray, Janet; Hein, C.; Smith, K.; Stephenson, M.; Grantham, H.; Finn, Judith; Stub, D.; Cameron, P.; Bernard, S. (2018)© 2018 Elsevier B.V. Introduction: Recent studies suggest the administration of 100% oxygen to hyperoxic levels following return-of-spontaneous-circulation (ROSC) post-cardiac arrest may be harmful. However, the feasibility ...
