Wir entwickeln katalytische Systeme, die mit erneuerbarer Energie Wasser und Restemissionen (z. B. CO₂) in saubere Kraftstoffe umwandeln – ein Beitrag gegen den Klimawandel. Unsere innovativen Photo- und Elektrokatalysatoren bieten hohe Effizienz und Selektivität bei der Umwandlung in grüne Moleküle. Indem wir grüne Kraftstoffe günstiger als fossile machen, gehen wir in eine CO₂-neutrale Zukunft.

Unsere Forschung an innovativer Photo- und Elektrokatalyse trägt aktiv zur Bekämpfung des Klimawandels bei und reduziert gesundheitliche Risiken durch fossile Brennstoffe. Die Katalyse-Systeme ermöglichen gleichzeitig die Erzeugung von grünem Wasserstoff und die Umwandlung von Treibhausgasen in wertvolle Produkte.
Unser Ziel ist die Entwicklung feldresponsiver Katalysatoren, die durch gezielte Manipulation aktiver Zentren mittels Spin-Kontrolle und Ferroelektrizitäts-Domänenmodulation hohe Effizienz erreichen. Grundlage sind bekannte Einflüsse externer magnetischer, elektrischer und mechanischer Felder auf die Katalyse-Leistung. Die atomaren Mechanismen der feldgekoppelten Reaktionen sind jedoch bislang nicht vollständig verstanden. Dazu kombinieren wir experimentelle Methoden wie XAS, Raman und TEM mit Multiskalen-Simulationen, um zu entschlüsseln, wie Felder Prozesse auf atomarer und elektronischer Ebene steuern.

Ein wichtiger Meilenstein ist die Skalierung von Labor-Elektrolyseuren auf industrielle Durchflusszellen mit Leistungsdichten über 1 A/cm² bei gleichbleibender Selektivität. So verbinden wir grundlegende Mechanismen mit ingenieurtechnischen Herausforderungen.
