A Database of Solution Additives Promoting Mg²⁺ Dehydration and the Onset of MgCO₃ Nucleation.

ABSTRACT: Formed via aqueous carbonation of Mg²⁺ ions, the crystallization of magnesite (MgCO₃) is a promising route to carbon capture and reuse, albeit limited by the slow precipitation of MgCO₃. Although magnesite is naturally abundant, forming at low temperature conditions, its industrial production is an energy-intensive process due to the temperatures required to prevent the formation of hydrated phases. The principal difficulty in aqueous conditions arises from the very strong Mg²⁺···H₂O interaction, with high barriers to Mg²⁺ dehydration. Using atomistic simulations, we have investigated the influence of 30 additive anions (X ^n-, n = 1-3), ranging from simple halides to more complex molecules, on the fi
