Enhancing MgO efficiency in CO₂ capture: engineered MgO/Mg(OH)₂ composites with Cl^-, SO₄^2-, and PO₄^3- additives.

ABSTRACT: The formation of a MgCO₃ shell hampers CO₂ capture efficiency in MgO. Our previous studies developed MgO/Mg(OH)₂ composites to facilitate CO₂ diffusion, improving capture efficiency. However, MgCO₃ still formed along the interfaces. To tackle this issue, we engineered the MgO/Mg(OH)₂ interfaces by incorporating Cl^-, SO₄^2-, and PO₄^3- additives. Novel MgO-H₂O-MgX (X = Cl^-, SO₄^2-, and PO₄^3-) composites were synthesized to explore the role of additives in preventing MgCO₃ formation. MgO-Mg(OH)₂-MgCl₂ nano-composites displayed enhanced CO₂ adsorption and stability. Th
