Description

A kind of mesoporous class zeolitic imidazolate framework material and preparation method and application
Technical field
The invention belongs to energy-saving and emission-reduction cleaning production field, be specifically related to a kind of mesoporous class zeolitic imidazolate framework material and Its preparation method and application.
Background technology
Although the development technique of the new forms of energy such as nuclear energy, solar energy, wind energy, tide energy, geothermal energy is increasingly mature, whole people In the energy resource structure of class society, ratio is also improving day by day.But in following decades, the mankind also will make with fossil energy For main energy source, and the consequence thus brought is exactly a large amount of artificial CO produced2The discharge of gas.Before the industrial revolution greatly CO in gas2Concentration is about 278ppm, and o. 11th " the greenhouse gas issued on November 19th, 2015 according to World Meteorological Organization Body publication " display, CO average in global atmosphere in 20142Molar fraction has reached before the industrial revolution the 143% of level, for 397.7ppm.And along with the fast development of global economy, since entering 21 century, CO in air2The balanced growth of concentration Speed is more than 2ppm/, even if the rate of rise of 2013 to 2014 has slowed down, also reaches 1.9ppm/, far above 20 The balanced growth speed (about 1.5ppm/) of the nineties in century.According to current CO2Discharge growth rate, by 2035, artificially Produce and be discharged into CO in air243,000,000,000 tons can be reached, will be that the whole world in 2009 artificially produces CO2The 150% of amount.
The CO of air middle and high concentration2Existence, can absorb and discharge the infra-red radiation from air to ground, this mistake again Journey, i.e. greenhouse effect, can cause average surface temperature more much higher than the situation not having this effect.Due to CO2In an atmosphere Concentration is far above steam or some other non-solidifying property greenhouse gases (such as methane, nitrous oxide and CFCs etc.), so CO2Being most important artificial greenhouse gases in air, the contribution to overall greenhouse effect about can account for 65%.Past 10 years The greenhouse effect value added of 83% and the greenhouse effect value added of 5 years 82% in the past are all by CO2Concentration growth causes.And Greenhouse effect can bring a series of serious consequences such as global climate deteriorates, and sea level rise, therefore uses various technology and absorption Absorbent carries out CO2Trapping and storage, become CO in reduction air2The task of top priority of concentration.
Current industrial many employing alkali liquor drip washing, organic base (monoethanolamine, diethanolamine etc.) absorb enrichment CO2.These Alkali liquid corrosion is relatively strong, can bring potential safety hazard for commercial production, and after absorption, or it is discarded to produce more absorption Thing, or circular regeneration power consumption is higher.Therefore in the urgent need to exploitation, corrosivity is relatively low, Cheap highly effective, the solid CO that is readily transported2 Adsorbent.
Zeolitic imidazolate framework material (Zeolitic Imdazolate Framework, ZIFs), is new the having of a class The metal of zeolite topological and machine framework material (Metal-Organic Frameworks, MOFs).It not only has similar In the highest heat stability of zeolite and chemical stability, and have porosity the highest for MOFs, big specific surface area with And the characteristic such as the adjustability in duct.ZIFs is to CO simultaneously2Having preferable affinity, this makes ZIFs at CO2Absorption and trapping aspect There is huge application prospect.ZIFs material can come control hole structure and size by selecting different organic ligands, passes through On organic ligand, the introducing of functional group improves the absorption to gas and separates.Such as, on part amido functional group or some The introducing of highly polar functional group, ZIFs material and CO2Between Interaction enhanced so that ZIFs material has higher CO2Absorption Performance.At present, the ZIFs material using target ligand synthesis is the most less, and CO2Absorption property needs to improve further, this Also be the present invention attempt solve problem.
Summary of the invention
In order to overcome the shortcoming of prior art with not enough, the primary and foremost purpose of the present invention is to provide a kind of mesoporous class zeolite miaow The preparation method of azoles ester framework material.Specifically, the present invention have no in have chosen 6 kinds of documents report with specificity official's energy The imdazole derivatives part of group, uses solvent thermal process synthesising mesoporous class zeolitic imidazolate framework material.
Another object of the present invention is to provide the mesoporous class zeolite imidazole ester bone prepared by above-mentioned preparation method Frame material.Framework material degree of crystallinity is higher, specific surface area is bigger for this, thermally-stabilised preferable with chemical stability.
