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.
