Electrospray mass spectrometric characterization of bimetallic group 8 — Gold clusters

Gold Bulletin Aims and scope Submit manuscript

Abstract

Bimetallic clusters containing gold in conjunction with Group 8 metals have been intensively studied as it is proposed that these compounds may find uses as catalysts or materials (or as precursors to catalysts/materials). These types of compounds are very difficult to characterize by the mass spectrometric techniques traditionally used to analyse transition metal clusters. In this paper we report a derivatization method employing electrospray ionization mass spectrometry that is reliable and informative for these types of compounds.

Additional information

Dr Dyson commenced his research career under the supervision of Professor Brian Johnson at The University of Cambridge working on the synthesis and characterization of ruthenium clusters. He moved with his supervisor to The University of Edinburgh where he completed his PhD. He then spent four years as a lecturer and Royal Society University Research Fellow at Imperial College, moving to The University of York in 1998. He also runs his own company, DMD Chiral Ltd, that is actively involved in the design and manufacture of chiral phosphine co-catalysts. Dr Bhalla obtained his PhD from the University of Manchester, moving to the University of East Anglia for a brief spell before moving to the University of York in 1997. Mr Lauterwasser is a student at Aachen University and spent a three month period in Dr Dyson’s research group at the University of York. Dr McIndoe obtained his PhD at The University of Waikato in New Zealand. Since 1998 he has been based at the University of Cambridge and works on a joint project spanning the Universities of Cambridge, Edinburgh and York.
