Molecular Electron-Transfer in Systems Relevant to Geological Sciences: Transport and Electrochemical Reactions in Compartments

电分析技术，特别是与分子电化学有关的技术（例如，循环伏安法）和具有由超微电极限定的横向分辨率的那些，将被应用以表征与地质科学相关的多孔系统中的化学（特别是催化）反应以及通过扩散、对流和/或迁移的质量传递。该项目涉及分子和颗粒尺度的过程。实验研究将伴随着理论建模方法。我们加强了对水和非水材料之间相界的化学和运输过程的了解，特别是在聚合（老化）时通过这种界面的时间依赖性运输。第二个主题将是详细的机制研究新的活性化合物的催化剂嵌入在多孔系统。最后，数值模拟将包括复杂的多孔基质安排内的电子转移，化学反应和各种运输类型的组合，并补充实验结果。

Electroanalytical techniques, in particular those related to molecular electrochemistry (e.g., cyclic voltammetry), and those with lateral resolution defined by ultramicroelectrodes, will be applied in order to characterize chemical, in particular catalytic, reactions as well as mass transport by diffusion, convection, and/or migration in porous systems of relevance to the geological sciences. The project deals with processes at the molecular and the grain scale. Experimental studies will be accompanied by theoretical modelling approaches. We enhance the knowledge about chemical and transport processes at the phase boundaries between water and non-aqueous material, in particular the time dependent transport through such an interface upon polymerisation (ageing). A second topic will be the detailed mechanistic study of new reactive compounds for catalysts embedded in porous systems. Finally, numerical modelling will include the combination of electron transfer, chemical reaction and various transport types within complex porous matrix arrangements, and complement the experimental results.
