Influence of Cations on Direct CO Capture and Mineral Film Formation: The Role of KCl and MgCl at the Air/Electrolyte/Iron Interface.

Uncovering the mechanisms associated with CO capture through mineralization is vital for addressing rising CO levels. Iron in planetary soils, the mineral cycle, and atmospheric dust react with CO through complex surface chemistry. Here, the effect of cations on the growth of carbonate films on iron surfaces was investigated.
