Robert James Baker
Assistant Professor, Chemistry


Dr Bob Baker was born in 1975 in Blaenavon, South Wales. He completed his undergraduate degree at the University of Warwick and carried out his PhD studies under the supervision of Prof. P. G. Edwards at Cardiff University (1997-2001) on early transition metal triphosphamacrocycles. He then worked as a postdoctoral research fellow with Prof. Cameron Jones (2001-2005), working on low oxidation state group 13 compounds. He was then awarded an Alexander von Humboldt Research Fellowship held at the Technische Universität Braunschweig, working with Prof. Dr. Matthias Tamm on substituted cyclohepatrienyl early transition metal complexes. From 2006-2008 he was a Lecturer in Inorganic Chemistry at Nottingham Trent University, before moving to Trinity College in January 2009. His research interests are in fundamental and applied actinide chemistry and the development of new transition metal complexes for catalysis

Research Expertise


My research focuses on the organometallic chemistry of p-, d- and f-block metals. Currently work in my group is centred on four different themes. 1. Low Oxidation State Actinide Chemistry. We are examining the coordination and organometallic chemistry of U(III), U(IV) and Th(IV)using a multi-technique approach in order to fully understand the electronic structure. Routinely we use X-ray diffraction, multinuclear NMR, UV-vis/NIR, infrared and raman spectroscopies, temperature dependent cyclic voltammetry and SQUID, as well as computational chemistry. Using these methodologies we are targeting a compehensive uderstanding of simple U(IV) compounds. The synthesis of compounds featuring An-An or An-TM (An = Th or U) multiple bonds is being undertaken in order to probe the effects of the f-orbitals in forming bonds. 2. High Oxidation State Uranium Chemistry. We are examining the catalytic activity of the uranyl ion towards hard monomers to probe new reactivity patterns for the uranyl ion. Additionally we are looking at reduction to the U(V)uranly ions. 3. New heterobimetallic transition metal complexes are being prepared with the aim of preparing new homogeneous catalysts for a variety of processes such as Fischer-Tropsch production of alkanes, and methane activation. 4. A new process is being developed in order to remove toxic metals (e.g. Cr, Cd, Hg, U, Pu) from contaminated soil, and precious metals from e-waste. From the crystal structures of fluorinated extractants we have characterised C-F...F-C interactions in the solid state and by computational chemistry.


  • Title
    • TOMEX - TOxic Metal EXtraction
  • Summary
    • The contamination of the environment by toxic metals is a major problem that can require expensive clean-up procedures. This project aims to develop an ex-situ soil re-mediation for a number of toxic metals using supercritical CO2 as a solvent. These can be broadly classed as actinide elements and heavy metal waste from industry and mining applications.

  • Title
    • Unusual Oxidation State Uranium Chemistry
  • Summary
    • We are exploring the chemistry of high oxidation state uranium chemistry. The elucidation of new reactivity pathyways that shed light on the 5f-orbital interaction will be explored. Furthermore, reduction to the Uranyl(V) ion will be explored.
