Abstract: Metallic tin was directly dissolved in ethylene glycol monomethyl ether and Sn(OCH2CH2OCH3)4 was obtained. The products were characterized by using FT-IR and Raman spectrum. The results show that direct electrochemical preparation of tin complexes has high current efficiency and electrolysis yield, and Sn(OCH2CH2OCH3)4 can be dissolved in ethanol solution and directly used as sol-gel precursor for preparation of nanometer SnO2. The results also show that nano-sized SnO2 prepared by this method has tetragonal cassiterite structure with a narrow size distribution of (10.0±0.4) nm.

Key words: Sn(OCH2CH2OCH3)4, 　Tin, 　Organic electrolysis preparation, 　Sol-gel, 　Nano-sized SnO2
