Renewable energy conversion by electrochemical activation of small molecules
Our research
Our research focus is on renewable energy conversion by electrochemical activation of small molecules such as H+, CO2, N2, O2 and H2O. We apply a variety of techniques including electrochemical, FTIR, XAS spectroelectrochemistry, DFT and stable isotope labelling to study the mechanisms of water oxidation, proton, CO2, O2 and N2 reduction reactions by molecular catalysts or biological enzymes.
