Sustainable energy production and storage is considered one of the major challenges of the future, as the burning of fossil fuels has a severe impact on our climate. One promising technology to meet this challenge is photocatalysis, which is inspired by the idea to use (sun)light for the generation of renewable fuels as e.g. hydrogen. State-of-the-art materials often comprise co-catalyst loaded semiconductors, but these systems are still limited in efficiency. The development of more powerful catalysts may have been hindered by lack of insights on a molecular scale, as the exact mechanistic details are so far surprisingly little understood. In this talk, detailed mechanisms of the hydrogen evolution on a titania model systems are presented and the consequences for the development of future catalyst materials are discussed.
