Definitions
- the invention relates to a method according to the preamble of claim 1.
- Nanotubes are needle-shaped tubes with a length of, for example, 1000 ⁇ and a diameter of several 100 ⁇ . They are separated or separable and are not specifically aligned spatially.
- the production of carbon nanotubes in an arc is known.
- the indirect production of transition metal oxide nanotubes is also known.
- Such a procedure is, for example, in the publication by SATISKUMAR, BC ET AL. : "Oxide nanotubes prepared using carbon nanotubes as templates" J. Mater. Res. 1997, 12, 604-606. With this method it should be possible to produce nanotubes from Si0 2 , Al 2 0 3 , V 2 0 5 and Mo0 3 . In this process, carbon nanotubes are used as templates.
- the carbon nanotubes are coated with tetraethyl orthosilicate, aluminum isopropoxide or vanadium pentoxide gel and then heated in air in order to oxidize the carbon.
- the process is very complex since carbon nanotubes have so far only been able to be produced in comparatively small quantities.
- a process for producing titanium oxide nanotubes by treating TiO 2 with aqueous sodium hydroxide solution and then reacting with aqueous hydrochloric acid (Adv. Mater. 1999, 11, 1307).
- a generic method that enables the direct production of transition metal oxide nanotubes results from the Applicant's WO 98/26871.
- a solution is made from a neutral surfactant molecule and a metal alkoxide.
- the solution is hydrolyzed and the precipitate aged.
- the aged precipitate is then heated.
- the neutral surfactant molecule is, for example, hexadecylamine and the metal alkoxide is a vanadium alkoxide.
- the nanotubes produced by this process are significantly more stable to oxidation than carbon nanotubes and show clear redox activities. They are suitable, among other things, as an active material for catalytic reactions.
- this process enables the production of large quantities of transition metal oxide nanotubes, since carbon nanotubes are not required as templates.
- the invention is based on the object of providing a method of the type mentioned which enables an even more cost-effective production of transition metal oxide nanotubes.
- an oxo acid of a transition metal oxide is used as a precursor.
- Such oxo acids can be obtained very inexpensively.
- a particularly suitable precursor is HV0 3 , which polymerizes spontaneously to V 2 O s .nH 2 0 and which can be produced very inexpensively. Its air stability enables easy work without special precautions.
- V 2 O s .nH 2 0 shows a very diverse intercalation chemistry, ie in addition to amines, many other compounds such as metal cations and alkylammonium ions can be incorporated.
- the method according to the invention makes it possible to further reduce the production costs by using inexpensive precursors that can be produced.
- other templates enable an extended functionalization of the nanotubes.
- the method enables the use of organic monomers such as, for example, aniline or 2,2 '-bithiophene as templates.
- FIG. 1 shows a transmission electron microscope image of transition metal oxide nanotubes which were produced by the method according to the invention, HV0 3 being used as the precursor and dodecylamine as the template
- FIG. 2 is an X-ray powder diagram of the nanotubes according to FIGS. 1 and FIG. 3 schematically shows the essential steps of the method according to the invention.
- a transition metal salt is converted into the corresponding acid H x TO y by ion exchange, as shown in FIG. 3.
- This acid polymerizes in water to the hydrated oxide 1, which according to FIG. 3 consists of several layers 2.
- structure 3 is a lamellar composite of template 4 as surfactant and the layers 2 made of a transition metal oxide.
- the regular layer spacings A are in the range of a few nanometers, for example in the case of vanadium oxide at 2.7 nm, the layer spacing A being dependent on the chain length of the template or of the amine RNH 2 .
- the layer structure 3 is converted into the tubular structure 5 shown schematically in FIG. 3 by a hydrothermal treatment. A preferred production process is described below, in which HV0 3 is used as precursor and dodecylamine is used as template.
- the product obtained by the hydrothermal reaction was filtered off, washed with ethanol and diethyl ether and air-dried. A black powder was obtained.
- Dodecylamine can be replaced by another neutral amine molecule.
- the quantitative ratio of the surfactant molecules with respect to vanadium is 1 to 2.
- the vanadium oxide nanotubes produced by this method are shown in FIG. 1 as a transmission electron micrograph.
- a typical X-ray powder diffractogram is shown in FIG. 2.
- HV0 3 another oxo acid of a transition metal oxide, for example molybdenum, can be used.
- organic monomers such as, for example, aniline or 2,2′-bithiophene are also possible as templates.
- the nanotubes produced by the method according to the invention have a lamellar wall structure with embedded templates 4 according to structure 5.
- the structure 5 shown is a single-layer spiral structure.
- the structure can also be multi-layered like a leek.
