In this study, synthesis of mesoporous SnO2 sphere was done by using polystyrene nanospheres (PS) and cetyltrimethylammonium bromide (CTAB) surfactant as hard and soft. The effect of temperature, atmosphere and calcination schedule on morphology of the particles were investigated. The templates were removed via calcination in air and mesoporous SnO2 particles were achieved. Mesoporous SnO2 spheres were characterized by Field emission electron microscopy (FESEM), Nitrogen adsorption/desorption and Fourier transform infrared analysis. The results determined surface area about 113.278 m2/g and particle size about 20-30 nm. These particles had nearly spherical morphology

Keywords: SnO2, mesoporous, PS latex, CTAB
