Li2SiO3 fast microwave-assisted hydrothermal synthesis and evaluation of its water vapor and CO2 absorption properties

- Nanocrystalline Li2SiO3 powders were synthesized via microwave-assisted hydrothermal method.
- Pure Li2SiO3 phase was obtained using short reaction time at low temperature.
- Li2SiO3 particles exhibited hollow sphere morphologies and high specific surface area.
- Water vapor and CO2 capture properties were evaluated by thermogravimetric analysis.
- Exhibited properties suggested potential applications of Li2SiO3 as catalyst and CO2 sorbents.
