In this work, we demonstrate our capabilities for determining reaction mechanisms and predicting macroscopic properties like faradaic efficiency using Grand-Canonical DFT (GC-DFT). Specifically, we examined the electrocatalytic nitrogen reduction reaction (NRR), which has been proposed as an alternative to the energy-intensive Haber Bosch process. GC-DFT identifies a dynmically re-arranging active site geometry that breaks intermediate scaling relations and allows for selective enhancement of NRR. Impressivley, our microkinetic model with GC-DFT inputs reproduces an experimentally measured current density and faradiac efficiency for this catalyst. Congratulations to Nick!
