Method for preparing ordered antimony-based oxide self-assembled nanometer cluster and nano-wire materials

The invention discloses a hydro-thermal synthesis method for antimony-based oxides (comprising antimonic oxychloride Sb8O11C12 and diantimony trioxide Sb2O3), which comprises the following steps: a solution of the trichloride antimony, ethanol and water is subjected to hydro-thermal reaction in a hydro-thermal reaction kettle taking polyfluortetraethylene as an inner lining at a temperature of between 160 and 200 DEG C for 2 to 20 hours, and then the precipitate is washed and dried to obtain antimony-based oxides with nanometer cluster or long nano-wire structures consisting of nano-rods. During the preparation, no any other surfactant is used, ordered structures of the antimony-based oxides are all formed by small and short nano-rods through self-assembly, and the flame-retardant properties of the antimony-based oxides can be greatly improved through theoretical analysis due to the ordered orientation arrangement structures of the antimony-based oxides.
