preparation example Construction

[0028] Such as figure 1 Shown, the preparation method of the aluminum-doped zinc oxide conductive powder of one embodiment, comprises the steps:

[0029] Step S110: according to the molar ratio of aluminum to zinc being 0.1:100-5:100, adding water-soluble aluminum salt to the aqueous solution of zinc salt with a concentration of 0.5 mol / L-3 mol / L to obtain a first mixed solution.

[0030] The aqueous solution of zinc salt with a concentration of 0.5mol / L~3mol / L is beneficial to the nucleation and growth of the product. If the concentration is too high, the growth rate of the product will be too fast, which is not conducive to the control of the morphology of the product.

[0031] The zinc salt may be a zinc salt commonly used in the art, preferably zinc nitrate, zinc chloride or zinc sulfate.

[0032] The water-soluble aluminum salt may be a water-soluble aluminum salt commonly used in the art, preferably aluminum nitrate nonahydrate or aluminum sulfate.

[0033] Step S120: ...

Embodiment 1

[0049] The preparation steps of the aluminum-doped zinc oxide conductive powder of the present embodiment are as follows:

[0050] (1) According to the molar ratio of aluminum to zinc of 0.4:100, add 0.03752g of aluminum nitrate nonahydrate to the aqueous solution of zinc nitrate with a concentration of 1mol / L to prepare 25ml of the first mixed solution.

[0051] (2) At a temperature of 0°C and under constant stirring, mix 35 ml of an aqueous solution of sodium hydroxide with a concentration of 3 mol / L and 3 ml of sodium dodecylbenzenesulfonate with a concentration of 0.1 mol / L The aqueous solution is simultaneously added dropwise to the first mixed solution to obtain a second mixed solution.

[0052] (3) Add 37 ml of deionized water to the second mixed solution, after stirring gently at room temperature for 1.5 hours, put it in an incubator and place it at 75°C for 8 hours to keep the reaction for 8 hours to obtain the reaction solution, centrifuge the reaction solution, and ...

In the aluminum-doped zinc oxide electric conduction powder, the molar ratio of aluminum to zinc is in a range of 0.1:100 to 5:100. The microstructure of the aluminum-doped zinc oxide electric conduction powder is complex. Further disclosed is a preparation method for the aluminum-doped zinc oxide electric conduction powder.

Description

technical field [0001] The invention relates to the field of photoelectric functional materials, in particular to an aluminum-doped zinc oxide conductive powder and a preparation method thereof. Background technique [0002] In the past few decades, nano-zinc oxide has attracted much attention due to its unique physical and chemical properties. Nano-zinc oxide has been widely used in many fields, such as solar cells, catalysis, varistors, optoelectronic devices, gas sensors and transistors. However, pure zinc oxide is easily affected by oxygen, carbon dioxide, hydrocarbons, water vapor and sulfide in the air during use, and its optical and electrical properties will decrease with the prolongation of use time. Studies have shown that the stability of zinc oxide in the air can be improved by doping, so that it can be better used in various fields. [0003] High-priced metals such as aluminum, indium and gallium have been successfully incorporated into the zinc oxide lattice ...
