Probing the Local Structure of Na in NaNO3-Promoted, MgO-Based CO2 Sorbents via X-ray Absorption Spectroscopy

Chemistry of Materials have published a paper by Rekhtina et Al about studies using “X-ray absorption spectroscopy (XAS) at the Na K-edge to interrogate the local structure of Na during the CO2 capture (MgO+CO2↔MgCO3)” with a view to providing “insight into the local structure of Na in MgO-based CO2 sorbents that are promoted with NaNO3”.

2 of Silson’s silicon nitride membranes of 500 nm thickness were used in the cell assembly: one membrane allowed for transmission of the beam onto the samples and the other membrane allowed for the collection of the fluorescence signal from the sample.
