Hydrogen: green and renewable energy sourced from sunlight and water
![Analysis of the photocatalysts before and after use, particularly by electron microscopy, will provide insights in improving photocatalysis activity and longevity.](/sites/default/files/styles/ua_landscape/public/media/images/2020-10/shearer-fig1-photocatalysis_h2_3.jpg?h=79efdc86&itok=yn9VnEe6)
Honours project: A renewable energy project that aims to develop your skills in inorganic synthesis, light initiated reactions, gas chromatography, electron microscopy and chemical engineering.

Exploring the fundamentals of photo-induced chemical reaction mechanisms
![Photocatalysis involves both electron and hole transfer, as well as molecular re-arrangement on a surface](/sites/default/files/styles/ua_landscape/public/media/images/2020-10/metha-photocatalysis.png?h=061ce4fd&itok=H65_vl68)
Honours project: Use high-speed lasers to initiate a water-splitting reaction to probe products for analysis.

Catalytic activity of metal clusters on surfaces
![Figure shows the HR-TEM image of the Au9 cluster deposited on a titania nanosheet. Scale bar is 0.5 nm](/sites/default/files/styles/ua_landscape/public/media/images/2019-05/metha-au9.png?h=e7b6955a&itok=wVbti4dw)
Honours project: Develop techniques to determine the geometric and electronic structure of size-specific clusters (e.g. Au9) deposited onto semiconductors surfaces (e.g. TiO2) and test their performance for photocatalytic water-spitting (H2 production) and CO2 reduction (hydrocarbon formation).
