Synthesis of new metal alkoxide is of importance in metal oxide chemistry. Particularly, metal alkoxides having moisture stable property are remarkably useful for producing high surface area metal oxides via sol-gel process due to capability to control the hydrolysis and condensation rates. Thus, in this work, synthesis of high surface area tin oxide is focused due to its excellent properties, such as, high chemical and mechanical stabilities, high conductivity and low resistivity. To achieve the goal, moisture stable tin glycolate synthesized directly from commercially available tin oxide and ethylene glycol via the Oxide One Pot Synthesis (OOPS) process is used as the precursor via the sol-gel technique. The effects of H₂O/acid ratios, aging time/temperature, calcinations time/temperature are discussed. The obtained structure of tin oxide is characterized using TGA, XRD, FT-IR and BET.
