Periodic Reporting for period 4 - N2FEED (N2 as Chemical Feedstock – Synthetic Nitrogen Fixation beyond Haber-Bosch)
Periodo di rendicontazione: 2019-12-01 al 2020-11-30
A) In the first work package we have continued to examine N2 splitting. New platforms were developed that undergo this challenging reaction and the chemical parameters that control the thermochemistry and kinetics of this reaction were examined.
B) Special emphasis was put on the coupling of charge and proton transfer which is of relevance for electrochemical approaches. Electrochemical N2 splitting was observed for the first time as proof-of-principle and is currently optimized.
C) We developed an efficient platform the enables the transfer of dintrogen from N2 into acetonitrile. This result already represents the realization of an important objective of the project.
1. Providing fundamentally new routes for the sustainable synthesis of nitrogen containing chemicals; impact is expected on the energy consumption and feedstock basis for such chemicals.
2. Giving insights into the relevance of correlated processes, such as thermal or photochemical proton coupled electron transfer, for multi electron redox transformations such as N2 fixation. These results will be instrumental for catalyst design also for other challenging reactions.
