Photocatalytic hydrogen production from water is a research area of immense interest as hydrogen has been identified as a potential energy carrier of the future. Most of the studied photocatalysts are inorganic and organic materials have been far less studied. Organic polymers have the potential advantage of being easily tunable through the use of a range of chemical building blocks.

Here, I will present our work on the application of conjugated materials as photocatalysts for hydrogen production from water. [1-3] We have used a range of different techniques that helped us to gain understanding of the properties that are important for the materials performance, including transient absorption spectroscopy. [4,5] Sacrificial water oxidation [6] and non-sacrificial overall water splitting [7] were also studied which shows the potential of these materials for the future clean energy generation. A focus of the presentation will be on processing of polymers into films and onto substrates, which will enable the fabrication of scale up devices going forward.[1,2,4]
