Preparation of porous SnO2 particles having high specific surface area and high thermal stability via an aqueous solution route and subsequent hydrothermal treatment
Hierarchically tailored SnO2 particles with a diameter of 200-500 nm were spontaneously formed in aqueous solutions dissolving SnF2 at 60 degreesC. The porous architecture of the particles was composed of SnO2 crystallites of ca. 5 nm in diameter and exhibited a high specific surface area of 130-230 m(2)/g. Subsequent hydrothermal treatment at 150 degreesC improved the thermal stability of the SnO2 fine structure.
