Description
Technical Field
The invention relates to the field of carbon material preparation, in particular to highly graphitized boron-doped dumbbell-shaped micro mesoporous carbon and a preparation method thereof.
Background
The micro-mesoporous carbon material has large specific surface area and pore volume, uniform and adjustable pore diameter and controllable morphology, effectively combines the high specific surface area generated by micropores and the high transmission efficiency of mesopores, and has wide application in the aspects of separation and adsorption of macromolecules, photoelectric micro devices and the like. Besides the performances, the micro-mesoporous carbon material has attractive prospects in the fields of supercapacitors, lithium ion batteries, fuel cells and the like.
At present, methods for synthesizing micro-mesoporous carbon materials mainly include a hard template method, an assembly method, a hydrothermal method and the like. The hard template method generally adopts a method of casting mesoporous silicon oxide by a carbon source and removing the hard template of silicon oxide after carbonization to prepare the micro mesoporous composite carbon material, but the method has the disadvantages of complex process, higher cost, long manufacturing period and difficulty in large-scale production, and the hard template method has higher requirements on precursors and templates. The method for preparing the micro-mesoporous carbon material by an assembly method is a method for synthesizing a micro-mesoporous composite carbon material by guiding a soluble pore-forming agent. The method omits the step of preparing the mesoporous silica hard template, and is more economical, reasonable, green and environment-friendly. At present, the method mainly takes resin formed by catalytic reaction of phenol and formaldehyde as a precursor, and obtains the porous carbon material through subsequent heat treatment. At present, most of monocyclic phenol and synthetic resin thereof are used as pore-forming agents, so that various properties of the prepared material are greatly limited, and the properties of the obtained carbon material cannot meet the application requirements easily. The hydrothermal method is to add water into a sealed container under high temperature and high pressure to perform chemical reaction on reactants in the sealed container so as to obtain the micro-mesoporous carbon material. Compared with the traditional preparation method, the hydrothermal method is green, environment-friendly, mild and fast, and the preparation process of the method reflects the ideas of green, environment-friendly and sustainable development of chemical preparation materials.
Researches show that the activation and doping modification of the carbon material can further improve the performance of the carbon material in various aspects. Methods for activating carbon materials are mainly divided into two main categories: chemical activation and physical activation. Chemical activation is by chemical agents such as ZnCl2KOH and H3PO4The carbon material and the carbon material are subjected to a series of crosslinking or polycondensation reactions, so that rich pores are created; the physical activation is carried out by reacting oxidizing gas such as air, carbon dioxide, and water vapor with carbon atoms in the carbon material at high temperatureAnd (4) reacting. The chemical activation has the advantages of short activation time and low activation temperature. However, the use of a large amount of chemical reagents increases the preparation cost, has strong corrosion effect on equipment at high temperature, needs a large amount of water in the washing process, and can meet the requirement of environmental protection and discharge after the wastewater is subjected to a complex treatment process. The physical activation has the advantages of simple and clean process, no need of washing after activation and contribution to meeting the requirement of large-scale industrial production. The carbon skeleton is doped with the hetero element (such as N, P, S, B, F) so as to obviously improve the surface properties of the carbon material, such as improving the wettability, the conductivity, the electrocatalytic performance and the like, and the carbon skeleton can also be used as an active site of reaction in electrochemistry.
In addition, the most important problem in the field of mesoporous carbon materials is how to meet the large-scale industrialization requirement, and on the other hand, as a novel carbon material, the carbon material plays an important role in the industrial field and is beneficial to realizing industrialized green production.
