Overcoming Nitrogen Reduction to Ammonia Detection Challenges: The Case for Leapfrogging to Gas Diffusion Electrode Platforms.

ABSTRACT: The nitrogen reduction reaction (NRR) is a promising pathway toward the decarbonization of ammonia (NH₃) production. However, unless practical challenges related to the detection of NH₃ are removed, confidence in published data and experimental throughput will remain low for experiments in aqueous electrolyte. In this perspective, we analyze these challenges from a system and instrumentation perspective. Through our analysis we show that detection challenges can be strongly reduced by switching from an H-cell to a gas diffusion electrode (GDE) cell design as a catalyst testing platform. Specifically, a GDE cell design is anticipated to allow for a reduction in the cost of crucial ¹⁵N₂ control experiments from €100-2000 to less than €10. A major d
