Description
Technical field
The invention belongs to the preparing technical field of carbon material, more particularly to a kind of phosphorus doping meso-porous carbon material and its microwave system
Preparation Method and application.
Background technology
The energy and environment are the two big key problems for influenceing current social development, the exploitation of the green suslainability energy and height
Effect utilizes extremely urgent.The development and utilization of the new green powers such as solar energy, nuclear energy, wind energy will make China in coming 10 years
As the big power generation state of the first in the world, the epoch of power surplus progressively arrive.And in recent years with " tesla " be representative base
Electricity consumption will be greatly stimulated in the rise of lithium ion battery and the pure electronic new-energy automobile of ultracapacitor, changes people
Energy-consuming pattern, while help to greatly improve the atmosphere polluting problem being on the rise.Pure electronic new-energy automobile it is big
Crowdization key is the performance and price of its energy-storage system.Therefore, the development and utilization of efficient, cheap energy storage material turns into new
The core hot issue in energy research field.
Carbon material with micro-nano structure such as graphene, CNT, carbon fiber, carbosphere and porous carbon etc. are only because of its
Special structure, high-specific surface area, good electric conductivity and excellent physics and chemical stability assign its high energy density,
Good cyclical stability and excellent high rate during charging-discharging, it is the high-performance electric chemistry energy storage material of great potential.
The large-scale application of energy-storage system based on carbon material depends on the game of its performance and price.For example, graphene is unique because of it
High-specific surface area (the ＞ 2600m that are assigned of structure2g-1) and excellent electric conductivity (electrical conductivity reaches 2000S-1cm-1), show
Excellent electrochemical energy storage performance.Graphene theoretical capacity as lithium ion battery electrode material reaches 744m Ah g-1, it is to pass
2 times of system graphite electrode；And its theoretical specific capacitance is up to 550F g when being used as super capacitance electrode material-1, it is carbon-based electric double layer
The limit of capacitor.
Porous carbon such as microporous carbon, mesoporous carbon and graded porous carbon etc. are because of its flourishing hole and good electric conductivity
A kind of preferable electrochemical energy storage materials, the electrochemical energy storage such as lithium ion battery and ultracapacitor system has been widely used in it
System.Compared to the carbon-based energy storage material such as graphene and CNT, porous carbon raw material sources enrich, and preparation method is simple and valency
Lattice are cheap, while to the electrochemical energy storage performance of analogy graphene can be obtained after its surface progress Heteroatom doping.At present, it is porous
Carbon is mainly obtained by chemical activation method, template and metal-organic framework compound (MOF) carbonizatin method.Chemical activation method
It is that raw material obtains through the activator such as KOH high-temperature process more with biomass, agriculture and industry waste etc., raw material sources enrich, and price is low
It is honest and clean.But a large amount of of activator use the secondary pollution for easily causing environment；The more networks formed with block copolymer of template

It is using the silicon substrate molecular sieve with loose structure as template, presoma removes silicon substrate template in template duct and obtained after high temperature cabonization
Obtain (hard template method).Template obtain porous carbon even aperture distribution it is orderly, beneficial to electrolyte solution electrode interior biography
Defeated and diffusion, the cycle performance and high rate performance of prepared electrode are excellent, but preparation method is cumbersome, is not easy to large-scale industry
Metaplasia is produced；Metal-organic framework compound (MOF) carbonizatin method preparation method is simple and direct, and prepared porous carbon hole is flourishing, electrochemistry
Energy-storage property is excellent, but MOF is expensive, and it is high to prepare cost.
Relative to traditional mode of heating, microwave heating passes through reactant internal dipole molecule and microwave electromagnetic field phase mutual coupling
High-frequency reciprocating motion caused by closing produces " interior frictional heat " heating response thing, and its energy consumption is only the part of traditional heating mode
Or 1/tens, and have the advantages that homogeneous heating, programming rate are fast, it has been widely used in aiding in synthesizing porous carbon energy storage
Material.Though microwave heating has the advantages of energy-efficient, by what its principle of heating was determined has selectivity to material
Add thermal property to cause carbonaceous presoma weaker to microwave absorption, there is no method to turn to the step microwave carbon of carbonaceous presoma one at this stage
The report of porous carbon materials, microwave heat the carbonization means for being only used as a kind of auxiliary, and its carbonized product also needs further high temperature to live
Change, the porous carbon materials that pyrolysis rear availability is excellent.
In summary, the problem of prior art is present be：
Existing template method is cumbersome, is not easy to large-scale industrial production；Metal-organic framework compound (MOF) carbon
It is expensive to change legal system Preparation Method MOF, it is high to prepare cost；The presoma of prior art is both needed under inert atmosphere protection high warm
Solution carbonization, equipment is complicated, and time-consuming, high energy consumption, is unfavorable for the large-scale industrial production of porous carbon；Therefore, develop energy consumption it is low,
The great scientific value of porous carbon novel preparation method and economy, Environmental Effect fast and simple and without activator and inert atmosphere protection
Benefit.
