Description

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.
