About the Project

Background: Electrochemical reduction of carbon dioxide at a copper surface, the carbon dioxide reduction reaction (CO2RR), is a potentially sustainable and scalable method of converting carbon dioxide into valuable molecules and delivering a low carbon future. The Parkin group have expertise in understanding how redox-enzyme structure controls biocatalysis (https://pubs.acs.org/doi/10.1021/ja073643o, https://www.pnas.org/content/112/47/14506, https://pubs.acs.org/doi/abs/10.1021/jacs.7b03611) and decorating electrode surfaces with near-monolayers of organic functionalities (https://pubs.acs.org/doi/10.1021/acs.langmuir.9b01254). The Douthwaite group are experts in solar-fuel production and are developing new carbon dioxide electro-reduction devices (https://chemistry-europe.onlinelibrary.wiley.com/doi/abs/10.1002/cctc.201800439, https://pubs.rsc.org/en/content/articlelanding/2017/TA/C7TA07509J#!divAbstract). The aim of this project is to unite this expertise to produce modified copper electrode surfaces, inspired by enzyme active site design, to yield improved product selectivity in CO2RR.

Objectives/Experimental Approaches: You will follow established Parkin group protocols to synthesise and characterise small molecules which you will electro-graft onto copper surfaces. You will be trained to characterise these new organic-functionalised copper materials using the cutting edge instruments in the University Nanocentre (https://www.york.ac.uk/nanocentre/). These new materials will then be tested for their CO2RR performance in electrochemical experiments conducted in the Douthwaite lab, with in-line gas chromatography product analysis and post-electrolysis NMR of the electrolyte. Promising materials will be stability tested before exploring if successful electrode-modifications can be combined with copper nano-structuring (collaboration with Dr Andrew Pratt, Physics).

Training: Appropriate training will be provided for all aspects of the work. All Chemistry research students have access to our innovative Doctoral Training in Chemistry (iDTC): cohort-based training to support the development of scientific, transferable and employability skills: https://www.york.ac.uk/chemistry/postgraduate/training/idtc/

The Department of Chemistry holds an Athena SWAN Gold Award and is committed to supporting equality and diversity for all staff and students. The Department strives to provide a working environment which allows all staff and students to contribute fully, to flourish, and to excel: https://www.york.ac.uk/chemistry/ed/.

You should hold or expect to achieve the equivalent of at least a UK upper second class degree in Chemistry or a related subject. Please check the entry requirements for your country: https://www.york.ac.uk/study/international/your-country/
