One of the greatest challenges of the 21st century will be securing cheap and renewable sources of energy. One of the most promising approaches to this challenge is to design catalysts from earth abundant materials capable of implementing key chemical reactions including the splitting water into hydrogen and oxygen (H2O → H2 + ½O2); the oxidation of hydrogen (H2→ 2H+) and reduction (2H+→ H2)...

Titanium alloys are widely used in aerospace applications due to their unique superiority of low density and high strength. In order to optimize the performance of Ti alloy, prior knowledge of the microstructure-property relationships and microstructural evolution as a result of processing should be studied.
Synchrotron radiation-based X-ray micro-computed tomography (SR µ-CT) has been...

Transition metal modified titania (M/TiO2, M = Pd, Pt or Au) photocatalysts have shown excellent activity for H2 production in alcohol-water mixtures under UV excitation [1, 2]. Recently, we have found that a 0.25 wt.% Pd-0.25 wt.% Au/TiO2 photocatalyst demonstrated a superior H2 production rate of 68 mmol g-1 h-1 compared to monometallic 0.50 wt.% Pd/TiO2 (43.0 mmol g-1 h-1) or 1.00 wt.%...

We have studied the long-range average and short-range local structures in Y2Ti2-xHfxO7 (x = 0-2.0) using diffraction and spectroscopy techniques respectively. Both neutron and synchrotron X-ray powder diffraction data show a clear phase transition of the average structure from ordered pyrochlore to disordered defect-fluorite at x ~ 1.6; the long-range anion disorder appears to develop...

Spin Crossover (SCO) is a phenomenon where a 3d4-7 metal ion reversibly switches between two electronic states, namely high spin (HS) and low spin (LS), under an external perturbation, such as temperature, pressure or light irradiation.[1] SCO behaviour is driven by short- and long-range lattice interactions which enables spin state cooperative propagation throughout the material, resulting in...

X-ray micro-beam Laue diffraction is a powerful tool for mapping the orientation and elastic strain within polycrystalline materials. Interactions between neighbouring grains influence the macroscale characteristics of a material, particularly its deformation behaviour, damage initiation and propagation mechanisms. Here we report on recent experiments using energy scanning diffraction of a...

Global energy concerns motivate the development of new and improved technologies for solar energy capture, with semiconductor photocatalysis expected to make an important contribution towards satisfying the energy needs of future societies. This talk will overview some of our recent research aimed at photocatalyst development for H2 production in alcohol-water mixtures, focussing primarily on...
