Composite oxides as next-generation photocatalysts for solar energy capture. This project aims to prepare new photocatalysts that capture and convert solar energy to stored energy by directly splitting water into oxygen and hydrogen, a perfectly clean and renewable fuel.

This project aims to prepare new photocatalysts that capture and convert solar energy to stored energy by directly splitting water into oxygen and hydrogen, a perfectly clean and renewable fuel. The project will use a "bottom-up" nanoscale approach, in which compounds with different chemical and electronic properties, but with compatible crystal structures in at least one dimension, are assembled in a single synthetic step to form a well-ordered composite. By making composites of compounds the band gaps - crucial to capturing light - and surfaces -crucial to evolving hydrogen and oxygen gas- of which complement each other, the project can deliver higher performing materials at a lower cost than can be achieved by conventional top-down modification. The project will deliver new and improved photocatalysts that will hasten progress towards commercially viable systems, helping to establish a new technology and putting pressure on competing technologies such as photovoltaics and wind to drive the renewables sector forward.Read moreRead less
Renewable solar hydrogen generated from waste streams. Sunlight is the largest available carbon-neutral energy source, with enough energy striking the planet in one hour to satisfy our current requirements for about a year. With the novel catalysts designed in this project, we will use this energy to simultaneously generate hydrogen and destroy organic pollutants by oxidation.
