Embodiment 1

[0021] (1) 0.2g ferrocene is completely dissolved in 50ml absolute ethanol;

[0022] (2) Drop 300ml of distilled water into the solution obtained in step (1) at a rate of 15mL / min, after the addition is complete, treat for 30 minutes under ultrasonic conditions;

[0023] (3) The solution obtained in step (2) was centrifuged at 2000 rpm for 20 minutes to obtain a precipitated product, washed three times with distilled water, and dried naturally to obtain the desired product.

[0024] The product obtained in the step (3) is characterized by its structure and morphology with XRD and TEM respectively (as figure 1 , figure 2 , image 3 Shown), the result shows that product is pure, and appearance is regular spherical, and particle size is at 40-45nm.

Embodiment 2

[0026] (1) 0.3g ferrocene is completely dissolved in 50ml absolute ethanol;

[0027] (2) 250ml of distilled water was dripped into the solution obtained in step (1) at a rate of 25mL / min, after the addition was completed, it was treated for 35 minutes under ultrasonic conditions;

[0028] (3) The solution obtained in step (2) was centrifuged at 1500 rpm for 25 minutes to obtain a precipitated product, washed 4 times with distilled water, and dried naturally to obtain the desired product.

[0029] The product obtained in the step (3) is characterized by XRD and TEM respectively for the structure and morphology of the product, and the result is the same as in Example 1, showing that the product is pure, the morphology is a regular spherical shape, and the particle size is 60-65nm.

Embodiment 3

[0031] (1) 0.4g ferrocene is completely dissolved in 50ml absolute ethanol;

[0032] (2) Drop 350ml of distilled water into the solution obtained in step (1) at a rate of 25mL / min, after the addition is complete, treat for 35 minutes under ultrasonic conditions;

[0033] (3) Centrifuge the solution obtained in step (2) at 1800 rpm for 22 minutes to obtain a precipitated product, wash with distilled water for 3-5 times, and dry naturally to obtain the desired product.

[0034] The product obtained in the step (3) was characterized by XRD and TEM respectively for the structure and morphology of the product, and the result was the same as in Example 1. The results showed that the product was pure, and the morphology was a regular spherical shape with a particle size of 70-80nm.

Abstract

The present invention relates to nanometer material technology, and is especially the preparation process of nanometer material of ferrocene and its derivative. The preparation process includes the following steps: dissolving ferrocene or its derivative in anhydrous alcohol to form solution of 0.004-0.008 g / ml concentration; dropping distilled water into the alcohol solution of ferrocene in certain speed and ultrasonically treating for 20-40 after finishing dropping; and final centrifugally separating to obtain precipitate, washing and naturally drying to spherical granular product of 40-110 nm size. The present invention has simple operation, easy control, easy industrial use, no environmental pollution and other advantages.

Description

technical field [0001] The invention belongs to the technical field of nanomaterials, and in particular relates to a preparation method of ferrocene nanomaterials. Background technique [0002] Organometallic chemistry is a subject with a long history and a young age. It is one of the frontier fields of contemporary chemistry, and its development is the most active, the fastest and the most vital. Since the discovery of ferrocene, its molecular structure and outstanding aromatic characteristics have aroused great interest among chemical scientists. Since then, the research work on the synthesis, properties and structure of ferrocene and its derivatives has been very active, and has been prosperous for decades. New species of ferrocene derivatives have emerged in an endless stream, opening up a new field of organometallic chemistry. Synthetic Derivatives mainly include single and multinuclear ferrocene complexes, ferrocene-based polymers, ferrocene molecular tree complexes, ...
