We work on the materials and interfaces that determine whether electrochemical energy conversion holds up outside a short experiment. Much of it starts from a durability question: bismuth and bismuth–antimony gas diffusion electrodes reduce CO₂ to formate efficiently for a while and then degrade, and we want to know what changes inside the catalyst layer as that happens, not only where it ends up.
A second line asks why some semiconductors repair themselves and how. Antimony chalcogenides such as Sb₂Se₃ and SbSeI undergo photoinduced phase transitions and recover from light-induced damage, and we use chemical bonding arguments and structural characterization to work out which defects move, what drives them, and whether those rules can be built into absorbers for the short-wave infrared.
The third question is about energy-efficient carbon capture. We build photoelectrodes that drive the capture-and-release cycle with sunlight, and membranes that capture and electrochemically convert CO₂ in a single assembly rather than two.
