Project Description

One PhD studentship funded by The Royal Society (with stipendiary support for four years) is available for a talented researcher with an interest in Inorganic Chemistry. The project will involve the synthesis and characterisation of new nanoscale metal-oxo cluster molecules and sits at the interface between molecular and materials chemistry.

Metal oxide materials are used in a multitude of modern applications including state-of-the-art self-cleaning windows, solar cells and antibacterial surfaces for next generation medical devices. Many of these applications stem from the ability of metal oxides to absorb light and use this energy to direct chemical reactions. As it can be challenging to optimise the properties of a given metal oxide, or to study the detailed reaction mechanisms that occur on a complicated surface, the Pike group synthesises and studies well-defined molecular metal-oxo clusters, which also exhibit exciting photo-active properties. This creates the opportunity to precisely tune properties, for instance to absorb the maximum amount of visible light whilst still driving the required chemical transformation, which will be essential for the design of new systems which can efficiently convert solar energy into fuels. This project will design tiny molecular versions of semiconducting metal oxides and will determine how to manipulate their properties by carefully optimising their size, composition and surface chemistry. These molecules will act as tiny reactive centres, which absorb light and catalyse reactions.

This ambitious project will examine how photophysical properties are affected by size and structure, in order to design new tuneable molecules which can be assembled into next-generation photoactive materials. These systems will be tested as photocatalysts for applications in solar fuel generation (e.g. splitting of water to generate hydrogen) and important chemical redox transformations. The applicant will build a wide range of skills in (air-sensitive) synthesis and characterisation, including an in-depth knowledge of NMR spectroscopy and X-ray crystallography, which will be supported by internal and external training programmes. The student will work closely with Dr. Pike as a key member of the research group. There will also be opportunities for national and international collaborations with experts in computational modelling and photoelectron spectroscopy.

The studentship comes with an associated travel budget for attending conferences/visiting collaborators and the opportunity to attend a specialised training school during the project.

Please direct informal enquiries and requests for further information to Dr. Seb Pike . For more information on the research interests of the Pike Research Group, please visit https://warwick.ac.uk/fac/sci/chemistry/research/pike/pikegroup/
