Template assisted synthesis of CaO-SnO2 nanocomposites

Calcium oxide (CaO) and tin oxide (SnO 2 ) with nanodimension have attracted significant attention as effective chemosorbents for toxic compounds. Hydrothermal method was used for the synthesis of highly porous CaO-SnO 2 nanocomposites by using sodium dodecylsulfate surfactant as a templating agent. Effect of concentration of surfactant as well as its critical micelle concentration (CMC) on the particle size of the nanocomposites was investigated. X-ray diffraction (XRD) was used to determine the crystal phases of these nanocomposites and particle size and morphology was identified by using transmission electron microscopy (TEM), scanning electron microscopy-energy dispersive X-ray (SEM/EDX) respectively. Furthermore thermo gravimetric analysis (TGA) and fourier transform infrared (FTIR) spectroscopy techniques were also used to characterize the CaO-SnO 2 nanocomposites.
