Hematite nanoparticles were reacted in a solution containing sulfide in contact with supercritical CO 2 , to simulate conditions relevant to carbon dioxide sequestration in the Earth's subsurface. X-ray diffraction was used to identify reaction products. Rietveld analysis of the X-ray diffractograms and thermogravimetric analysis were used to estimate the amounts of reaction product formed...
The transformation of ferrihydrite to siderite (FeCO 3 ) in the presence of supercritical CO 2 (scCO 2 ) and aqueous sulfide has been investigated by in situ attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR) and ex situ X-ray diffraction (XRD). The chemical transformation of iron-bearing minerals to form iron carbonates may play a role in the chemistry...
