Description
Technical field
The invention belongs to photochemistry field, be specifically related to a kind of CO2And N2Photochemical reduction method, it is adaptable to the energy, environment
Exploitation Deng gas resource available in field.
Background technology
The burning of Fossil fuel remains current topmost energy supply means, but is as the continuous exploitation of the resource-type energy, China
The energy and shortage of resources national conditions the severeest.Meanwhile, along with a large amount of CO during the use of fossil-fueled2Release, greatly
CO in gas2The rising of concentration causes the insulation effect of earth surface further substantially, result in the appearance of global warming phenomenon.Cause
This, developing while new alternate resources, solve the greenhouse gases that resource consumption brought exceed standard, the ring such as trade waste pollution
Border problem is imperative.
It is known that CO2And N2It is two kinds of gases that in air, content is more, and carbon, the nitrogen contained by both gas is first
Necessary basic element in element or industrial and agricultural production.Carbon compound is not only and is constituted the basic of organism, or
Main energy supply material；And nitrogen element is except participating in organism protein, the composition of hormone, the metabolism of regulation organism,
The also production with the chemicals such as chemical fertilizer, pesticide is closely related.Therefore, under mild conditions, it is achieved CO2And N2Molecule
Effectively utilize most important for building a resource-conserving society.In recent years, researchers have developed a series of CO2And N2
Method of reducing, wherein homogeneous photoreduction gains great popularity owing to it is simple to operate and conversion efficiency is high.But, present stage
CO2And N2Reduction reaction is still faced with many obstructions: (1) CO2And N2The physicochemical properties of molecule are relatively stable, molecule
Structural rearrangement needed for activation can be high, such as CO2The single electron activation barrier of reduction is up to-1.9V.Therefore, higher activation
Potential barrier becomes CO2And N2" the reaction bottleneck " of reduction reaction.(2)CO2Or N2It is former that the generation of reduzate generally requires hydrogen
Son or the participation of proton, and traditional photochemical systems typically use organic sacrificial agent as hydrogen atom and proton donor, such as three
Ethamine, triethanolamine and Tricyclic amine etc..The use of organic sacrificial agent and organic solvent not only adds the cost of reduction reaction, instead
The discharge answering waste material also adds burden to environmental improvement.
Summary of the invention
The technical problem to be solved is the deficiency for conventional, prior art, it is provided that a kind of with water as proton donor, profit
Photoreduction CO is promoted with sodium sulfite2And N2New method.The inventive method utilizes the high energy that sodium sulfite photodissociation produces
Aqueous electron and hydrogen atom, it is achieved that CO2And N2The direct activation of molecule, overcome tradition photochemical systems in " bottleneck is anti-
Should ".Meanwhile, this method has also abandoned traditional organic sacrificial agent, is successfully realized CO in water environment economic, that clean2
To HCOOH and N2To NH4 +Efficient Conversion, have efficiently, environmental friendliness, selectivity height, non-secondary pollution etc. excellent
Point.
The present invention solves that the technical scheme that problem set forth above is used is:
One utilizes sodium sulfite to promote photochemical systems reduction CO2And N2Method, it is characterised in that: in water add Asia
Sodium sulfate, and it is passed through CO2Or N2, controlling system pH is 5.0～9.0, at the purple that can make sodium sulfite generation photosensitivity reaction
Under the conditions of external exposure, system is carried out ultra-vioket radiation and realize CO2And N2Reduction.
By such scheme, the concentration of described sodium sulfite is 25～100 mM/ls.

Joint.
By such scheme, the wavelength of described ultra-vioket radiation light source need to be less than 270nm.
By such scheme, it is stirred system before described ultra-vioket radiation making its mix homogeneously.
By such scheme, described CO2Reduzate is HCOOH；N2Reduzate is NH4 +。
By such scheme, described CO2Or N2Gas first passes through the Drexel bottle including redistilled water, then passes to Na2SO3Molten
Liquid system is reduced.Thus can avoid along with reaction is carried out, Na2SO3Solution evaporation excessive velocities.
The method utilizes Na2SO3As sensitiser absorption ultraviolet light, and generate high energy aqueous electron.Meanwhile, Na2SO3Pass through
Hydrolysis is captured the proton in water and is generated NaHSO3, NaHSO3Hydrogen atom can be quickly produced under the attack of aqueous electron.
The reduction of inert molecule is realized under the synergism of hydrogen atom and high energy aqueous electron.As at CO2In reduction experiment, hydration electricity
Son can direct and CO2Molecule combines, by CO2Molecule effective activation is to CO2 ·-.Then, the hydrogen atom in system and CO2 ·-
Spontaneous combination generates HCOOH, and this system HCOOH cumulative production of four hours is about 26mg/L.At N2Reduction experiment
In, first it is hydrogen atom and N2In conjunction with completing N2Activation, then via a series of hydrogen atom additive reaction generate N2H4
Molecule.Finally, N2H4Molecule is eventually converted into NH by follow-up electronics-proton translocation approach4 +, this system eight hours
NH4 +Cumulative production is 6.65mg/L.At N2In reduction experiment, NaHSO3Not only contribute to the generation of system hydrogen atom, its
More weak proton affinity also makes NaHSO3Become and compare H2The proton donor that O is the most excellent.Thus aqueous electron and
NaHSO3N can be effectively facilitated respectively as electron donor and proton donor2Electronics-proton translocation approach in reduction experiment
Occur, thus accelerate N2H4Molecule is to NH4 +Conversion.
It is an advantage of the current invention that:
1、Na2SO3Being the conventional raw material of industry, its preparation method is the most ripe, wide material sources, and its photoreaction converts and produces eventually
Thing is Na2SO4, do not result in secondary pollution.
2, reaction condition is gentle, and normal temperature and pressure gets final product fast reaction, it is not necessary to complex appts, simple to operate, without dangerous, and nothing
Professional need to be engaged to operate.
3, the proton donor of reaction is water, it is not necessary to organic sacrificial agent and the addition of organic solvent, environmentally friendly.
4, the present invention uses Na2SO3Making photosensitizer, can not only induce the generation of high energy aqueous electron, it further hydrolyzes product
Thing NaHSO3Can also the producing and follow-up proton transfer of promotion system active hydrogen atom, thus increase substantially CO2With
N2Reduction efficiency.This system has higher selectivity of product, and its reduction effect is substantially better than common KI photoreduction
System.
