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.
Photocatalyst Activity Indicator Inks (Paii’s) are now featured on Wikipedia. The inks were pioneered by the Mills group over a number years, and development of newer, improved ‘smart inks’ for detecting the activity of photocatalytic surfaces is ongoing.
A simple, inexpensive method for the rapid testing of the photocatalytic activity of self-cleaning surfaces
A paper, published by the Mills group on November 14th, 2013, detailing a proposed ISO standard test for the testing of the activity of self-cleaning surfaces using a simple, inexpensive method, has been receiving considerable interest within the scientific community.
