The samples were characterized by X-ray diffraction, thermogravimetric/differential thermal analysis, N2 adsorption-desorption, transmission electron microscopy and scanning electron microscopy techniques. The obtained results showed that the samples have mesoporous structure with high surface area and nanocrystalline structure with crystals in the range of 3-6nm. Moreover, the effects of calcination temperature on the structural properties of the samples were investigated. The sample calcined at 500°C showed the highest surface area (340.1m2/g) and pore volume (0.56cm3/g). With further increasing in calcination temperature the surface area decreased due to sintering and destruction and coalescence of the pores.
