PhD in Solar Energy Harvesting

Fig 1

Solar energy harvesting is the direct conversion of sunlight to fuels.  My methods involve the use of bi-phasic catalysts to split water when under the influence of sunlight.

TiO2 has for many years been the pinnacle of photocatalytic research.  Doped TiO2 has shown much promise in applications with wide ranging consequence.  Another source of interest is in pure TiO2 but using the synergistic relationship between the different crystal structures.  Mixtures of both anatase and rutile have shown promise and are indeed the main composition of the commercial P25.

My new synthetic procedures allows for the production of bi-phasic nanoparticles.  Single particles consisting of half anatase and half rutile. These nanoparticles have allowed some interesting measurements to be carried out and helped to answer one of the big questions of semiconductor photocatalysis.  This is regarding the band alignment in a composite system of Anatase and Rutile.  Our Nature Materials paper on the revision of the band alignments of anatase and rutile we showed how this works.2015-01-16 10.20.43

This project will explore the plethora of different materials that could be married together using this synthetic technique and assess the composites for the use as solar energy harvesting photocatlaysts.

This project will also involve the design modification and optimization of an engineering device that will measure hydrogen produced in these reactions.  as well as having an outreach element where members of the public can be enthused as to the benefits of hydrogen.
