preparation example Construction

[0021] The present invention discloses a fullerene C 60 The preparation method of derivative electrocatalyst, preparation steps are as follows:

[0022] S1. Take 800.0mg fullerene C 60 Dissolve in 300.0mL p-xylene, stir well to make fullerene C 60 After dissolving, add 30mL propylenediamine to the solution, then use a magnetic stirrer to stir the above mixture at room temperature until the fullerene C 60 Till the dark purple fades;

[0023] S2. Use a glass rod to drain the magnetically stirred mixed solution into a separatory funnel, let it stand for stratification, and collect the lower suspension with a beaker;

[0024] S3. Wash the suspension once with 0.1mol / L hydrochloric acid solution, pour the washed suspension into a centrifuge tube for centrifugation at a speed of 10000r / min, and centrifuge for 10min. After centrifugation, wash with deionized water until suspension The solution is neutral, and then put the centrifuged and washed solid into a vacuum drying oven for...

Embodiment 1

[0027] 1) Fullerene C reacted with organic base 60 Derivatives Preparation

[0028] Take 800.0mg fullerene C 60 Dissolve in 300.0mL p-xylene, stir well with a stirring bar to make fullerene C 60 Dissolve completely, then add 30mL propylenediamine to the solution, then use a magnetic stirrer to stir the above mixture at room temperature until the fullerene C 60 Till the dark purple fades;

[0029] Then use a glass rod to drain the magnetically stirred mixed solution into a separatory funnel, let it stand for stratification, and present the lower layer of suspension, the upper layer of colorless liquid, and the lower layer of suspension is the required sample liquid, which is collected with a beaker. During the collection process, the suspension in the lower layer flows down the wall of the beaker;

[0030] Then wash the suspension once with 0.1mol / L hydrochloric acid solution, pour the washed suspension into a centrifuge tube for centrifugation, the centrifugal speed is 100...

Abstract

The invention discloses a preparation method of a fullerene C60 derived electrocatalyst, and relates to the technical field of catalyst preparation. The preparation method comprises the following steps: dissolving 800.0 mg of fullerene C60 in 300.0 mL of p-xylene, stirring, adding 30 mL of propane diamine, and then magnetically stirring; draining the mixed liquid obtained after stirring into a separating funnel, standing for layering, and collecting lower-layer turbid liquid; the turbid liquid is washed with a 0.1 mol / L hydrochloric acid solution, centrifugation and washing are conducted after washing, and after the turbid liquid is neutral, the turbid liquid is put into a vacuum drying oven to be dried; taking 200.0 mg of a dried sample, placing the dried sample in a porcelain boat, placing the porcelain boat in a vacuum tube furnace for calcination, introducing nitrogen into the vacuum tube furnace at a flow rate of 50-100 ml / min, heating to 300-700 DEG C at a heating rate of 5-10 DEG C / min, and keeping the temperature for 2-6 hours to obtain the fullerene C60 derivative electrocatalyst. The method disclosed by the invention is simple, convenient and rapid, and the fullerene C60 derivative electrocatalyst prepared by the method disclosed by the invention has a stable graphitized structure and excellent electrocatalytic oxygen reduction performance.
