Abstract
Mechanical activation of quartz grains in a dry atmosphere causes triboelectric charging that can capture CO 2 quantitatively (Thøgersen et al., https://doi.org/10.1016/j.cplett.2021.139069). Based on electron structure calculations, we propose a mechanism for this process. According to the mechanism, CO 2 is inserted in the quartz lattice to form an anchored CO 3 moiety. Predicted 13C chemical shifts of this product agree with solid-state 13C NMR measurements.
