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.
