The research interests of the Mills group are wide and varied including: dye and semiconductor photochemistry, redox catalysis (in particular, oxygen catalysis), solar energy conversion (in particular artificial photosynthesis) and colour and fluorescence based indicators and smart inks and plastic films.
The second in a series of papers to be published by the photocatalytic activity indicator inks consortium is now available for download. It describes in detail the analysis method, that is a proposed ISO standard, for detecting the activity of a semiconductor photocatalyst on a range of surfaces, using a simple, reproducible technique.
