preparation example Construction

[0016] A rapid preparation method of nano-scale amorphous carbon, which may specifically include: in a nitrogen glove box, firstly perform dehydration and deoxygenation operations on an organic solvent, and then seal the alkali metal in a transparent container containing the dehydrated and deoxygenated organic solvent. container, and the opening of the transparent container is sealed; then, the transparent container is taken out from the nitrogen glove box, and the transparent container is placed on the solid-state laser workbench in the air, and the transparent container in the transparent container is The organic solvent is subjected to liquid-phase laser ablation, so that nano-scale amorphous carbon can be rapidly prepared.

[0017] Specifically, the rapid preparation method of the nanoscale amorphous carbon may include the following embodiments:

[0018] (1) The protective gas can be at least one of nitrogen or rare gas.

[0019] (2) The alkali metal can be at least one o...

Embodiment 1

[0025] A rapid preparation method of nanoscale amorphous carbon may specifically include the following steps:

[0026] Step 1. In a nitrogen glove box, place 200mL of toluene and 20g of flaked potassium in the same beaker, and then heat it to 90°C while stirring, and keep it for 90min to remove oxygen and water from toluene, thereby Toluene that has been dehydrated and deoxygenated is obtained.

[0027] Step 2. In the nitrogen glove box, take 20mL of toluene that has been dehydrated and deoxygenated from the beaker, and take 10mg of rubidium metal from the ampoule, transfer the two to a transparent sample bottle, and put the The bottle mouth was sealed, and then the transparent sample bottle was taken out from the nitrogen glove box.

[0028] Step 3. Place the transparent sample bottle on a solid-state laser workbench, and use a neodymium-doped yttrium aluminum garnet solid laser (Nd:YAG) to perform liquid-phase laser ablation on the organic solvent in the transparent sample ...

Abstract

The invention discloses a rapid preparation method of nanoscale amorphous carbon. The rapid preparation method comprises the following steps: in an environment protected by protective gas, putting alkali metal and a dewatered and deoxygenated organic solvent into the same transparent container, and sealing an opening of the transparent container; and then, carrying out liquid-phase laser ablationon the organic solvent in the transparent container by adopting laser so as to prepare the nanoscale amorphous carbon. According to the method, the nano-sized amorphous carbon can be rapidly preparedat room temperature, and the preparation method is simple in process and easy to operate.

Description

technical field [0001] The invention relates to the field of amorphous carbon, in particular to a rapid preparation method of nanoscale amorphous carbon. Background technique [0002] Amorphous carbon has no fixed morphology and structure, has high specific surface area, good chemical stability, and unique carrier transport properties, so it is expected to be widely used in catalysis, adsorption, and energy conversion. [0003] At present, the preparation methods of amorphous carbon mainly rely on vapor phase deposition and high-temperature carbonization of organic matter. The vapor phase deposition method mainly uses H 2 Reductive gases such as reducing organic gases to carbon at high temperature, and using solid substrates to collect; for example: "Realization of continuous Zachariasencarbon monolayer" in the article "Realization of continuous Zachariasencarbon monolayer" in Volume 3, Issue 2, Pages 1-8 of "SCIENCE ADVANCES", 2017 In order to grow a single-layer amorphou...
