Abstract

We report on the synthesis of nanocrystalline lithium silicate by coupling of sol–gel method in reverse microemulsion. The sample calcined at 800 ºC gives pure phase lithium metasilicate nanocrystallites. X-ray diffraction and transmission electron microscopy confirmed the formation of nanocrystalline lithium silicate particles with a narrow size distribution. The nanoparticle prepared in the microemulsion shows enhanced CO2 sorption capacity and shorter retention times at higher temperature (~ 131 ml/g at STP at 610 ºC) which are better than the best known results.
