Description
Summary:The reverse microemulsion mediated sol-gel synthesis of lithium silicate nanoparticles under ambient conditions was presented. X-ray diffraction and transmission electron microscopy confirmed the formation of nanocrystalline lithium silicate particles with a narrow size distribution. The higher-temperature sorption measurements for carbon dioxide were carried out using a volumetric technique. The nanoparticle prepared in the microemulsion showed enhanced carbon dioxide sorption capacity and shorter retention time at higher temperature that were better than the best known results. TEM study showed that the final nanoparticles size was between 4 and 12 nm with uniform distribution of spherical particles. It was found that the nanomaterial was good for carbon dioxide sequestration at higher temperature.
