Project B07 examines single crystal perovskite-based (BaTiO3 and SrTiO3) electrocatalysts for the oxygen evolution reaction in water splitting electrolyzers. The interaction of interfacial states, chemical reaction intermediates, and electronic structure of perovskite model systems and how they determine catalyst activity and stability is investigated on a fundamental level by advanced surface science methods. Fermi level engineering via targeted doping and defect chemistry is pursued to minimize losses due to kinetic overpotentials and to enhance stability of the OER catalytically active surface phase. Project B07 is closely collaborating with the other catalytic projects receiving samples and providing analytic data.

项目B07研究了用于水裂解电解槽中析氧反应的单晶钙钛矿基（BaTiO 3和SrTiO 3）电催化剂。界面状态，化学反应中间体和钙钛矿模型系统的电子结构的相互作用，以及它们如何决定催化剂的活性和稳定性，通过先进的表面科学方法在基础水平上进行了研究。追求通过有针对性的掺杂和缺陷化学的费米能级工程，以最大限度地减少由于动力学过电位的损失，并提高OER催化活性表面相的稳定性。项目B07正在与其他催化项目密切合作，接收样品并提供分析数据。
