Abstract: 
Photocatalytic hydrogen production from water is a research area of immense interest. Most of the studied photocatalysts are inorganic and organic materials have been far less studied. Here, I will present our work on the application of conjugated materials as photocatalysts for sacrificial hydrogen production from water.1,2

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.3-5 Sacrificial water oxidation,6 non-sacrificial overall water splitting,7,8 and carbon dioxide reduction, were also studied which showcases the potential of these materials for the future.
