Microstructural and Structural Characterization of Materials for CO2 storage using Multi-Scale X-Ray Scattering Methods
Greeshma Gadikota, Andrew J. Allen
A multi-scale understanding of CO2 interactions with natural materials is essential for engineering the safe and permanent storage of CO2 in geologic formations. Towards this end, the use of ultra small-, small-, and wide-angle X-ray scattering methods (USAXS/SAXS/WAXS) bridges our current understanding between theoretical nano-scale material interactions with CO2 and large-scale trapping and percolation pathways of CO2 in geologic formations. The latest advancements in synchrotron radiation have enabled multi-scale microstructural and structural characterization of geologic materials with CO2. In this book chapter, we compare the use of X-ray scattering techniques with other microstructural material measurement techniques, discuss the fundamental relationships governing the scattering measurements and microstructural properties such as the surface area, porosity, , and illustrate the application of USAXS/SAXS/WAXS methods for the adsorption of CO2 on Na-montmorillonite containing a monolayer of interlayer water.
