Abstract

Mechanical activation (i.e., tumbling) of quartz sand in a carbon dioxide (CO₂) atmosphere leads to triboelectric charging of the sand grains, driving a process that ultimately sequesters and removes CO₂ from the ambient atmosphere. Supported by diffuse reflectance FTIR and ¹³C solid-state NMR experiments and density functional theory (DFT) calculations, we propose that CO₂ is inserted into the quartz lattice to form an anchored CO₃ species, a process that otherwise requires high temperature and pressure to proceed synthetically. The products of the reaction are stable for at least 6 months at ambient temperature and pressure, but CO₂ is liberated at temperatures above 150 °C. The prospect of using this method to remove CO₂ from the atmosphere and, ultimately, to help mitigate the adverse effects of greenhouse gases and global warming is briefly discussed.
