Current Position

Eamon has moved on to the Solids4Fun doctoral school at the Technical University of Vienna and is working in the Theoretical Chemistry group under Prof. Peter Blaha. Solids4Fun seeks to improve the interdisciplinary communications between physicists, chemists and material scientists, and to this end Eamon is continuing his experimental work with soft X-ray spectroscopy as well as increasing his focus on calculations using DFT and other codes.

Research Projects

g-C3N4 carbon-nitride photocatalyst

A post-carbon energy infrastructure will rely on two primary energy carriers: electricity and hydrogen fuel. At present time hydrogen is less economic to use in energy applications than conventional fossil fuel sources, limiting it to niche markets. Advanced materials design and nanotechnology offer the possibility of producing and using hydrogen in a more economic and sustainable fashion.

I am using synchrotron radiation and soft X-ray techniques to study the electronic properties of a crystalline poly(triazine-imide) (PTI) compound with interstitial lithium and chlorine. PTI compounds have been demonstrated to catalyze the splitting of water into oxygen and hydrogen gas under illumination without the addition of precious metal catalysts. The material has the potential to be a stable, inexpensive method to generate hydrogen fuel from water.

(Ga1-xZnx)(N1-xOx) photocatalyst

Visible light photocatalysis of water splitting has also been reported in a solid solution between GaN and ZnO. The material exhibits a reduced bandgap significantly lower than either precursor, indicating an opportunity to optimize and further reduce it to improve photoabsorption.
