Abstract

Formation of corrosion products on zinc was investigated with in-situ Raman and FTIR when exposed to wet supercritical carbon dioxide (scCO₂) and subsequent depressurization. Zinc oxide (ZnO) and smithsonite (ZnCO₃) formed on zinc in scCO₂. The dissolved water precipitated as liquid water in the reaction cell during depressurization. Formation of ZnO, ZnCO₃ and a needle-like zinc hydroxy carbonate species on zinc was observed inside a sessile water droplet during conditions simulating the depressurization phase. Addition of oxygen accelerated the formation of the carbonate species due to higher cathodic activity that increased zinc dissolution.
