In this AI-generated episode of The Zero Emission Zone, we break down a 2025 perspective by Seger et al. on the dominant reaction mechanisms in CO₂ electrolysis. From C1 to elusive C3 products, this work synthesizes computational and experimental data into a coherent map of how CO₂ transforms into fuels and chemicals on copper catalysts. Listen in as we explore the formal rules that may unlock cleaner fuel production through electrified chemistry.
