The promoting effect of alkali nitrates molten salt on the CO2 capture capacity a commercial MgO was investigated in detail. In particular, ratio Li/Na/K and loading mixture particles were optimized, influence calcination adsorption temperatures evaluated. sample doped with 10 mol % (Li0.3Na0.6K0.1)NO3 demonstrated to possess highest uptake (up 16.8 mmol g–1), which is value reported for based adsorbents literature. adsorption/desorption cycling stability studied using both temperature swing...
Optimization of MgO adsorbents is predominantly focused on the regulation appropriate adsorption sites for CO2 associated with Mg2+-O2– low coordination. Here, first time, we conducted transient kinetic experiments to identify and characterize changes molecular path in MgO-based upon addition molten salt modifiers. Among optimized samples, 10 mol % NaNO2 surface exhibited highest uptake (15.7 mmol g–1) at 350 °C compared less than 0.1 g–1 unpromoted MgO. Kinetic modeling showed that...
In this review the CO<sub>2</sub> adsorption mechanisms of MOF-74-Mg, HKUST-1, SIFSIX-3-M, and ZIF-8 are explored, highlighting their preferential sites, CO<sub>2</sub>–MOF complex configuration, dynamics, bonding angle, water stability.
Abstract CO 2 reduction is crucial if the effects of this gas on global warming are to be alleviated.

The optimization of MgO-based adsorbents as advanced CO2 -capture materials is predominantly focused on their molten-salt modification, for which theoretical and experimental contributions provide great insights high performance. underlying mechanism the promotion effect molten salt capture, however, a topic controversy. Herein, characterization techniques, including in situ environmental transmission electron microscopy (eTEM) chemisorption by diffuse-reflectance infrared Fourier transform...
In this work, we report on a novel sodium dodecyl sulfate (SDS)-assisted magnesium oxide (MgO)-based porous adsorbent synthesized by hydrothermal method for intermediate CO2 capture.
