Embodiment 1

[0042] Embodiment 1, preparation InOOH ultrafine nanowire and In 2 o3 The whole process of nanocube.

[0043] 0.1g of InCl 3 4H 2 o 3 The powder is dissolved in 5ml of oleylamine, and 8ml of absolute ethanol is dropped into it during the ultrasonic process. After the solution is clarified, the mixed solution is poured into a sealed reaction kettle and heated for reaction. When heating, the heating rate is set to 8°C / min. When the reaction temperature is 120°C and the reaction time is 12 hours, the reaction kettle is naturally cooled to room temperature, the product is centrifuged, washed with absolute ethanol, and dried to obtain a white powder, which is indium oxyhydroxide ultrafine nanowires .

[0044] Using the above-mentioned similar preparation process, when the reaction temperature is 180° C. and the reaction time is 24 hours, a white powder is obtained, which is indium oxide nanocubes.

[0045] figure 1 , 2 are respectively given the InOOH ultrafine nanowires an...

Embodiment 2

[0052] According to the batching and preparation process of Example 1, the reaction temperature is still 120° C., but the reaction time is changed to 24 hours. The obtained InOOH nanowires are basically the same as in Example 1.

Embodiment 3

[0054] According to the batching and preparation process of Example 1, only the reaction temperature was changed to 130° C., and the reaction time was changed to 12 hours.

[0055] Figure 9 Shown is the TEM picture of the product prepared under the above conditions. It can be seen that a small amount of nanoparticle aggregates appear in the obtained InOOH nanowires.

Abstract

The invention relates to a method for preparing hydroxyl indium oxide nanowires and indium oxide nano particles and belongs to the technical field of nano material preparation. The method for preparing the hydroxyl indium oxide nanowires and indium oxide nano particles comprises the steps of: dissolving InCl3.4H2O powder in oleylamine, and dropwise dding absolute ethyl alcohol under ultrasonic condition until the mixed solution is clear; heating the mixed solution to 120-210 DEG C at a temperature rise rate of 4-8 DEG C / min and reacting for 12-24 hours, thus obtaining the hydroxyl indium oxide nanowires or / and indium oxide nano particles. The method for preparing the hydroxyl indium oxide nanowires and indium oxide nano particles has the advantages that a heating manner is changed, so that a reaction temperature is greatly reduced due to adoption of a high temperature rise rate, reaction time is shortened, and energy consumption and loss of equipment caused by high temperature are reduced; product composition and morphology are controlled through change of temperature rise rate or reaction temperature; meanwhile, the method for preparing the hydroxyl indium oxide nanowires and indium oxide nano particles is relatively safe, simple and reliable and has good repeatability.
