Leif Hammarström Group

The Hammarström Group works on fundamental mechanistic studies related to artificial photosynthesis and photoredox catalysis, using laser-spectroscopy, photochemical and electrochemical methods. We are part of the Swedish Consortium for Artificial Photosynthesis. Our studies are focused on design and study of molecular systems for controlling photoinduced electron transfer and proton-coupled electron transfer, and for coupling photoinduced charge separation to multi-electron reactions.

The EU-project SoFiA is coordinated by Leif Hammarström.

Welcome to the Leif Hammarström research group, to the right you will see a list of our research. Follow the links to read more about specific research areas.

We work on fundamental mechanisms of photoinduced and proton-coupled electron transfer reactions, in molecular and molecule/semiconductor systems. We work with experimental tools to distinguish step-wise and concerted proton-coupled electron transfer mechanisms, and determine conditions allowing for concerted reactions in multi-electron/-proton reactions.

We study synthetic catalysts for H2 production, CO2 reduction and water splitting to understand the catalytic cycle. By a combination of spectroscopic, photochemical and electrochemical methods we capture intermediates and study critical reaction steps.

We also study electron transfer dynamics in dye-sensitized photocathodes of p-type materials (e.g. NiO). They open for the possibility of tandem solar cells for high photovoltage devices and for solar fuels generation with molecular catalysts, where H2 production and water splitting occur in separate half-cell reactions.
