Elemental mercury oxidation and adsorption on magnesite powder modified by Mn at low temperature

- It is a new idea to investigate the removal of elemental mercury over Mn/MgO at low temperature.
- The amorphous MnO2 and chemisorbed O2 played key roles on the removal of elemental mercury.
- Combined in situ FTIR with XPS and TG, the possible oxidation and adsorption mechanism is proposed and MnHgO3 is the product of elemental mercury oxidation over Mn/MgO.
