Spectroelectrochemical Investigation of Low-dimensional van der Waals Electrocatalysts

We are sorry, this position has been filled.

This project will be based around the use of in situ Raman spectroscopy to aid in the development of novel electrocatalysts based on low dimensional van der Waals (vdW) materials such as molybdenum disulfide. Electrocatalysts are key components of emerging electrochemical technologies such as electrolyzers and fuels cells, which are expected to be important for a clean energy future in which it will be necessary to convert between electricity generated by renewable solar or wind resources and chemical fuels such as hydrogen. This project will be experimental in nature, and involve the use of Raman spectroscopy to study the structure of vdW electrocatalysts while they are operating in the electrochemical environment under various conditions. Electroanalytical techniques will be employed to evaluate electrocatalyst performance, which will be correlated with structural changes observed by Raman spectroscopy. The student will also explore the effect of varying substrate properties, synthesis conditions, and operating conditions on the electrocatalytic performance of the electrodes. Research will be conducted in an interdisciplinary and collaborative environment.
