| Application: | Sodium carbonate can be used as: • Pore-inducing agent to synthesize Fe-based oxygen reduction catalysts. • An alkaline solid sorbent to capture CO2 in flue gases. • A precursor to synthesize high magnesium-bearing calcites in the pure phase. It can also be used to modify the internal structure of the ZSM-5 catalyst, for conducting methanol to gasoline reactions. |
| Biochem/physiol Actions: | Buffer component, may be used for the removal of peripheral membrane proteins. |
