Abstract

The invention relates to alpha-TeO2 of a micro structure, which is of an alpha-TeO2 material with the thickness of 0.5 to 1 micrometer, the width of 3 to 5 micrometer and close-packed small wafers. The alpha-TeO2 is made by adopting Beta-TeO2 as the raw material to be hydrothermal treated in the water solution of NaOH and NH4NO3. The alpha-TeO2 of the micro structure can be used as an excellent tellurium-source to prepare combined metal oxide catalyst. The invention discloses a production method of alpha-TeO2.

Description

technical field

[0001] The present invention relates to microstructured α-TeO 2 And preparation method and use. technical background

[0002] α-TeO 2 It has strong refraction, piezoelectricity and excellent acousto-optic properties [see Physical Review B 5 (1972) 4087], and has important applications in the fields of science and engineering. However, there are fewer chemical methods, most of which are physical methods such as laser evaporation [see J.Mater.Sci.32 (1997) 6595 and Inorganic Chemistry Communications 7 (2004) 179] and physical deposition methods [see Cryst.Res. Prepared by Technol.40 (2005) 1023]. The more common chemical preparation method is to take tellurium isopropoxide (IV) as raw material, the gel-sol method in alcoholic solution, but involves many steps, needs to strictly control the fast hydrolysis rate of tellurium isopropoxide [see J . Non-Cry. Solids 345-346 (2004) 634 and Mater. Lett. 59 (2005) 2379]. No chemical method has been used to prepare ...
