Artificial carbon fixation to organic materials is an important challenge to address the global warming issue. However, the currently prevalent strategies rely upon catalysts to overcome the high kinetic barrier in CO 2 chemistry. We show that water‐sealed dielectric barrier discharge in atmospheric CO 2 affords a facile and selective carbon fixation pathway to performic acid. To verify the unique mechanism of catalyst‐free one‐pot ideal sequence for carbon fixation, we present in‐depth analysis of how the process is controlled by various discharge parameters. We validate the vibrational excitation of CO 2 as the major driving force for the reaction and illuminate the central role of the plasma/liquid‐water interface.
