Aperture and roughness govern iron oxide passivation in olivine fractures during carbon mineralization

Year: 2026

Type: article

Abstract: Rougher surfaces in smaller apertures olivine fractures increase reactive surface area but hinder efficient carbon dioxide mineralization by promoting passivating iron oxide precipitates, according to an integrated experimental and modeling study.
