Abstract
The antimony-doped SnO 2 nanocrystallite was synthesised by the co-precipitation reaction and subsequent calcination from the antimony(III) chloride and tin(IV) chloride. The crystal size, pore size distribution and properties of the nanocrystalline powders were examined by differential thermal analysis, thermogravimetric analysis, X-ray diffraction and desorption isotherm(Barrett–Joyner–Halenda method). Calcination of the precipitate powder at 650°C led to the formation of Sb–SnO 2 nanocrystallite of ∼6 nm in crystal size. Most of the pores in the nanocrystallite are about 5–10 nm in diameter. Effect of doped antimony on the crystal size of the nanocrystallite is discussed.
