摘要：

The samples of lithium zirconium silicate were prepared by precipitation, template and sol-gel methods. The samples were prepared with several mol ratios of Li:Zr:Si. The preparation of lithium zirconium silicate samples by precipitation method were carried out by using the lithium nitrate, zirconyl nitrate, zirconium(IV) oxypropoxide and tetramethylorthosilicate (TEOS) as precursors. The samples of lithium zirconium silicate were prepared by using cetyltrimethyl-ammonium bromide (C-TAB) and tetramethyl ammonium hydroxide (TMAOH) by template method. The samples of lithium zirconium silicate were characterized by XRD, TEM, SEM, Si-29-MAS NMR and FTIR. The surface area, alkalinity / acidity of the samples of lithium zirconium silicate were measured. The TGA analysis of lithium zirconium silicate samples was done. The CO2 captured by the samples of lithium zirconium silicate was estimated. The captured CO2 by the samples of lithium zirconium silicate was found to be in the range 3.3 to 8.6 wt%.
