The present project aims at establishing suitable electrode/electrolyte combinations for the electrocatalytic and photoelectrocatalytic reduction of N2 (NRR). In particular, ionic liquids(IL)-based electrolytes, 3D nanostructured electrodes, and novel catalyst materials based on non-noble metal chalcogenides which mimic the natural role model of the catalytic centers of nitrogenases will be investigated. We also plan to compare photoelectrocatalytic and electrocatalytic NRR in identical two-compartment cells to identify similarities and prerequisites for both types of reaction schemes, in accordance with the main spirit of the SPP. We intend to create an understanding between the electrode structure and composition with the potential catalysts, the reaction environment controlled by the electrolyte, and the reaction performed under electrochemical and photoelectrochemical conditions. Therefore, novel ILs realized during the project will be also immobilized on and within fibrous structures, e.g. using the electrospinning approach, and the effect of improved 3-phase boundaries and shortened diffusion paths for educt, product and charge carriers on NRR performance will be determined.

本项目的目的是建立合适的电极/电解质组合的电催化和光电催化还原N2（NRR）。特别是，离子液体（IL）为基础的电解质，3D纳米结构电极，和新型催化剂材料的基础上非贵金属硫族化物模仿固氮酶的催化中心的自然角色模型将进行研究。我们还计划比较光电催化和电催化NRR在相同的两室细胞，以确定这两种类型的反应方案的相似性和先决条件，根据SPP的主要精神。我们打算在电极结构和组成与潜在的催化剂，由电解质控制的反应环境，以及在电化学和光电化学条件下进行的反应之间建立理解。因此，在该项目期间实现的新型离子液体也将固定在纤维结构上和纤维结构内，例如使用静电纺丝方法，并且将确定改进的三相边界和缩短的离析物、产物和电荷载体的扩散路径对NRR性能的影响。
