Abstract
The method for preparing mono-dispersed nano zinc oxide granules includes the following steps: (1). dissolving zinc acetate in absolute ethanol or absolute methanol, fully stirring them at zero deg.C to obtain suspended liquor whose concentration is 0.5-30%, dissolving lithium hydroxide in absolute ethanol or absolute methanol at room temperature to obtain lithium hydroxide solution whose molar concentration is twice that of zinc acetate; (2). under the temperature of zero deg.C drop-by-drop adding isopyknic lithium hydroxide solution to stirring zinc acetate solution to obtain white colloidal mixed solution; (3). placing the colloidal solution into a hydrothermal reactor, heat-insulating for 1-3 hr, at 80-200 deg.C, taking out the reaction solution; and (4). cetnrifugally-separating said reaction solution, fully washing said separated material by using absolute ethanol, drying at room temp. so as to obtain the invented product.
Description
Technical field
The present invention relates to prepare the method for nano granular of zinc oxide in monodisperse.
Background technology
Nano-ZnO is a kind of novel high function fine inorganic material, because it has quantum size effect, small-size effect, surface effects and macro quanta tunnel effect, thereby nano-ZnO produced not available these effects of its body phase material, represented many special nature: photoabsorption, optical filtering, antibiotic, anti-aging.At aspects such as medicine, magneticmedium, photoelectricity wide application is arranged.Nano zine oxide can also improve wear-resisting, the resistance to tearing of rubber, and improves comprehensive mechanical performance.The antibacterial of nano zine oxide uniqueness makes it be widely used in senior antibiosis and self-cleaning snitaryware, floor tile, coating, plastics etc., and its electricity and excellent in optical properties can be used to make voltage dependent resistor, fluor, image recording material etc.The difficult single controlled preparation that realizes the zinc oxide granularity of existing sol-gel preparation method, the single nano ZnO material of size distribution synthetic have very big difficulty.
Summary of the invention
The purpose of this invention is to provide a kind of controlled method for preparing nano granular of zinc oxide in monodisperse.
The method for preparing nano granular of zinc oxide in monodisperse of the present invention is characterized in that may further comprise the steps:
1) zinc acetate is dissolved in dehydrated alcohol or the anhydrous methanol, 0 ℃ is fully stirred down, be mixed with concentration and be 0.5～30% suspension liquid, under the room temperature lithium hydroxide is dissolved in dehydrated alcohol or the anhydrous methanol, be mixed with the lithium hydroxide solution that volumetric molar concentration doubles zinc acetate;
2) under 0 ℃ of temperature, with isopyknic lithium hydroxide solution, dropwise join in the zinc acetate solution that is stirring, get white colloidal mixing solutions;
3) above-mentioned colloidal solution is put into hydrothermal reaction kettle,, be incubated 1～3 hour down, take out reaction soln at 80～200 ℃ with the reactor after the sealing;
4) the above-mentioned reaction soln of centrifugation,, dry under the room temperature with dehydrated alcohol to the isolate thorough washing, promptly get nano granular of zinc oxide in monodisperse.
The present invention has the following advantages:
1. the raw materials cost of preparation nano zine oxide is cheap, technology is easy, do not need the pH value of regulator solution, operation easy to implement.
2. the narrow diameter distribution of prepared nano zine oxide, by the conditioned reaction substrate concentration, temperature of reaction kettle can be controlled the size of nano granular of zinc oxide.
3. temperature of reaction is low, and the product recovery that can circulate is a kind of preparation method of energy-conserving and environment-protective.
Description of drawings
Fig. 1 is the transmission electron microscope photo of product.
Embodiment
The single example that disperses Zinc oxide nanoparticle of the inventive method preparation:
Zinc acetate is dissolved in the dehydrated alcohol, and 0 ℃ is stirred down fully that to be mixed with concentration be 2% suspension liquid, at room temperature lithium hydroxide is dissolved in the dehydrated alcohol, is mixed with lithium hydroxide solution, and its volumetric molar concentration is the twice of zinc acetate solution.Adopt dropper isopyknic lithium hydroxide solution dropwise to be joined in the zinc acetate solution that is stirring, mixing solutions maintains 0 ℃.With above-mentioned mixing solutions, be sealed in the autoclave then, be incubated 2 hours down at 120 ℃, the centrifugation reaction soln, behind the dehydrated alcohol thorough washing, drying promptly obtains the single Zinc oxide nanoparticle of diameter Distribution, and the transmission electron microscope photo of product is seen Fig. 1.
