Omvandling av förnybar energi genom elektrokemisk aktivering av små molekyler
Vår forskning
Vårt forskningsfokus ligger på omvandling av förnybar energi genom elektrokemisk aktivering av små molekyler som H+, CO2, N2, O2 och H2O. Vi använder en mängd olika tekniker inklusive elektrokemisk, FTIR, XAS-spektroelektrokemi, DFT och stabil isotopmärkning för att studera mekanismerna för vattenoxidation, proton-, CO2-, O2- och N2-reduktionsreaktioner av molekylära katalysatorer eller biologiska enzymer.
