Embodiment 1

[0022] Example 1: 36g of iron oleate and 5.7g of oleic acid were dissolved in 200g of octadecene, and reacted at 320°C for 30min under the protection of nitrogen to obtain iron ferric oxide nanoparticles with a particle size of about 10nm. The obtained nanoparticles are dissolved in n-hexane, and the solvent is evaporated to obtain highly ordered oleic acid-coated nanomaterials. Calcining the obtained material at a high temperature of 500° C. for 2 hours can obtain highly ordered carbon-coated ferric oxide nanoparticles. The obtained material was etched away with ferric oxide with hydrochloric acid to obtain a mesoporous carbon material with a particle size of about 10 nm. Its specific surface area can be 1600m 2 / g.

Embodiment 2

[0023] Example 2: Dissolve 36g of iron oleate and 8.55g of oleic acid in 300g of octadecene, and react at 330°C for 60min under the protection of nitrogen to obtain iron ferric oxide nanoparticles with a particle size of about 14nm. The obtained nanoparticles are dissolved in n-hexane, and the solvent is evaporated to obtain highly ordered oleic acid-coated nanomaterials. Calcining the obtained material at a high temperature of 500° C. for 2 hours can obtain highly ordered carbon-coated ferric oxide nanoparticles. The obtained material was etched away with ferric oxide with hydrochloric acid to obtain a mesoporous carbon material with a particle size of about 14 nm.

Embodiment 3

[0024] Example 3: 72g of iron oleate and 5.7g of oleic acid were dissolved in 200g of hexadecene, and reacted at 280°C for 90min under the protection of nitrogen to obtain ferric oxide nanoparticles with a particle size of about 6nm. The obtained nanoparticles are dissolved in n-hexane, and the solvent is evaporated to obtain highly ordered oleic acid-coated nanomaterials. Calcining the obtained material at a high temperature of 500° C. for 2 hours can obtain highly ordered carbon-coated ferric oxide nanoparticles. The obtained material was etched away with ferric oxide with hydrochloric acid to obtain a mesoporous carbon material with a particle size of about 6 nm.

Abstract

The invention belongs to the technical field of inorganic material, and specifically relates to a preparation method of a highly-ordered mesoporous carbon material. The preparation method comprises the following steps: subjecting iron oleate to cracking reactions so as to obtain oleic acid-coated Fe3O4 nano particles; dissolving the obtained nano particles in n-hexane, drying the solvent to make the nano particles carry out arrangement and assembly, then subjecting the nano particles to high-temperature carbonization so as to obtain highly-ordered carbon-coated Fe3O4 nano particles; and finally etching off the nano particles so as to obtain the highly-order mesoporous carbon material. The preparation method has the advantages of simpleness, easily available raw materials, and low cost. Mesoporous carbon materials with different particle sizes and morphologies can be obtained by controlling the particle size and morphology of Fe3O4 nano particles. The provided highly-ordered mesoporous carbon material has an extremely high specific surface area, and thus has a very wide application prospect in fields such as drug carriers, wastewater treatment, and the like.

Description

technical field [0001] The invention belongs to the technical field of inorganic materials, and in particular relates to a preparation method of a highly ordered mesoporous carbon material. Background technique [0002] Due to its huge specific surface area and pore volume, mesoporous carbon has a very strong adsorption capacity, so it plays a very important role in adsorbents, and also makes it a catalyst carrier, electrode material, hydrogen storage material, etc. It has very important application prospects. In addition, mesoporous carbon also has the advantages of high temperature resistance, acid and alkali resistance, electrical conductivity and heat transfer. [0003] At present, the main preparation methods of mesoporous carbon are: (1) hard template method, which uses ordered mesoporous silicon as a template and synthesizes ordered mesoporous carbon materials by casting method. This method is simple in principle, but the steps are complicated, and additional templa...
