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.
Starting November, visiting PhD student Eva Jiminez will be joining the group for a 3 month placement to evaluate semiconductor photocatalyst containing concrete samples using Professor Andrew Mills’ rapid activity indicator inks.
In 2015, the Mills group had the great privilege of having Pperng Surachai Khankaew (pictured left) as a visiting young researcher to work on a joint project between Professor Andrew Mills (pictured centre) and Professor Panuwat Suppakul (pictured right).
He remained with the group for 7 months and had a tremendous impact on everyone working with him.
The Mills group sent representatives to the Harwell campus in Oxfordshire to give talks and presentations on their work on semiconductor photocatalysis and SODIS. The campus was open to the public, and over the course of the day over 15,000 people passed through to see the cutting edge in science and engineering.
A tutorial review article, published in Chemical Society Reviews by Professor Andrew Mills and Mr Nathan Wells, outlines the groups work on reductive photocatalysis and its various practical applications.
Mills group members Dr O’Rourke and Dr Hazafy flew out to Japan to visit an exhibition on self-cleaning materials, and discuss the groups efforts to introduce a new ISO standard for measuring the activity of self-cleaning surfaces.
The paper entitled ‘Smart, reusable labels for assessing self-cleaning films‘, has been selected to feature as the front cover article for Chemical Communications Issue 20, 2015. The paper describes a simple test for detecting the presence, and assessing the activity, of semiconductor photocatalyst thing films using an adhesive indicator
Supervisor: Prof. A Mills; Second supervisor: Prof. Hardacre
Start date: 1st Oct 2015; duration: 3 years; qualifying candidates: UK citizens with a 1st class degree in Chemistry or Chemical Engineering by 1st October 2015.
Semiconductor photocatalysis is emerging as a significant new photochemical process for creating innovative commercial products, such as: self-cleaning glass, concrete and tiles. However, to date attention has been restricted to ambient temperature applications of the technology and in this project we explore its application at elevated temperatures. In particular, we will use semiconductor photocatalysis to mediate gas phase reactions of commercial significance, at lower temperatures than the conventional thermal catalytic reactions. These reaction will include: alcohol reforming, steam reforming, the water-gas shift reaction and environmental air clean-up reactions, such as NOx and ozone removal. The PhD candidate will receive training not only in thermal catalysis but also photocatalysis, using a variety of techniques including: DRIFTS-MS, BET, SEM, TEM and laser-driven, time-resolved transient absorption spectroscopy. This research area is very new and so open to many new discoveries and challenges; thus, the project is only really suitable for a highly motivated candidate seeking a project with adventure and panache.

A recent paper, to be published in Chemical Communications, written by Andrew Mills and Nathan Wells, has been highlighted in a Chemistry World article. The article describes a new method of detecting commercial semiconductor photocatalysts to assess their ‘self-cleaning’ ability, and represents quite a step forward for activity testing.
Dr David Hazafy has been awarded the Enterprise Fellowship, and will spin out a company based on research and knowledge developed in our group
Enterprise Fellowships provide funding and support to outstanding entrepreneurial engineering researchers, working at a UK University, to enable them to develop a spin-out business around their technological idea.
Enterprise Fellows receive up to £85,000 in seed funding, salary support and benefit from having a year to take time out from their research to focus completely on spinning out a business.
Enterprise Fellows are also invited to join the Academy’s Enterprise Hub where they receive ongoing support and business mentoring from the Academy’s Fellowship, which includes some of the UK’s most successful technology entrepreneurs and business leaders.
