In this project, the main fundamental focus is set on revealing factors responsible for the activity and selectivity, which are related not only to electrodes but also electrolytes through electrolyte composition. The target is to develop electrocatalysts and electrolyte compositions capable to tune selectivity with respect to the anodic reactions (which typically have gaseous O2 as the final compound) during electrolysis of aqueous solutions. In particular, we aim to directly generate H2O2 at the electrode surface and/or selectively oxidize N-compounds, such as amines, using pure electrochemical pathways or using the generated H2O2 for "in-pot" oxidation of the N-compounds chemically at the interface (in-situ chemical-electrochemical approach).

在这个项目中，主要的基本焦点放在揭示影响活性和选择性的因素上，这些因素不仅与电极有关，而且通过电解液的组成与电解液有关。其目标是开发能够在电解水溶液期间相对于阳极反应(通常以气态O2为最终化合物)调节选择性的电催化剂和电解液组合物。特别是，我们的目标是直接在电极表面生成过氧化氢和/或选择性地氧化N-化合物，如胺，使用纯电化学途径或使用生成的过氧化氢在界面上化学地“在锅中”氧化N-化合物(原位化学-电化学法)。
