在乙二醇甲醚溶液中电解合成ZnTiO3超细粉末
Synthesis of Nano-sized Particle Spinel ZnTiO3 by Electrolysis in CH3OCH2CH2OH Solution
摘要
Abstract
Zinc and titanium alkoxide was prepared in the cell without diaphragm when the titanium sheet was electrolysed for 6 h and then zinc sheet was electrolysed for 3 h tetrabutylammonium (0.035 mol ·dm-3) bromides were added to serve as supporting electrolyte. Glycol and methyl ether were used as electrolyte. Current density of 30 A · dm-2 and temperature of 30 ℃ were employed. The current efficiency was 95.4％. The structure of precursor was analyzed by laser Raman spectra,infrared spectroscopy. The xerogel was prepared by vacuum drying for 24 h after hydrolyzi. The obtained xerogel were calcined at 450 ℃, 2 h in air. After 2 h, the nano ZnTiO3 were prepared successfully. The structural characterization of the xerogeld and nano ZnTiO3 was performed by X-ray diffraction (XRD), transmission electron microscopy (TEM). The results indicated that ZnTiO3 nano-partieles (size 20-30 nm) are obtained. The grain of xerogel was about 25 nm. The product is high purity.关键词
