Description
Technical field
The invention belongs to chemical field, is related to a kind of catalyst, relates in particular to one kind and is used for high-performance photocatalytic-oxidation
Change the nano-TiO of power-plant flue gas mercury2/g-C3N4Photochemical catalyst.
Background technology
Mercury as a kind of extremely toxic substance, have high volatile, easily in vivo with the property such as permanent enrichment in food chain,
Environmental and human health impacts are caused greatly to endanger, extensive attention has been caused to its emission control.Coal combustion is main people
For mercury emissions source, every year because the mercury that fire coal is discharged accounts for 40% or so of anthropogenic discharge, wherein power plant accounts for 35% or so in China.
It is the demercuration technology that more forward position is sayed at present using photocatalysis oxidation technique.In recent years, g-C3N4As a kind of visible light-inducing,
Intermediate band gap and the non-metal semiconductive of high stability and be widely studied.But g-C3N4Specific surface area is smaller, quantum efficiency
More low factor limits its further commercial Application.Therefore, it is actively developed and develops with high-specific surface area and high quantum
The new technology and new technology of efficiency sample, which are always that researchers are insistent, to pursue a goal.
The content of the invention
For above-mentioned technical problem of the prior art, the invention provides one kind to be used for high-performance optical catalysis oxidation power plant
The nano-TiO of gas mercury2/g-C3N4Photochemical catalyst, the described this nanometer for high-performance optical catalysis oxidation power-plant flue gas mercury
TiO2/g-C3N4Photochemical catalyst will solve g-C of the prior art3N4Specific surface area is smaller, quantum efficiency is more low influences catalysis
The technical problem of effect.
The invention provides a kind of preparation method of the adjustable titania modified graphite phase carbon nitride photochemical catalyst of dimension,
First by g-C3N4Presoma is positioned in Muffle furnace, the high-temperature calcination at a temperature of 400 DEG C -600 DEG C, described g-C3N4Forerunner
Body high-temperature calcination temperature ramp is incubated 2h-4h between 2 DEG C/min-10 DEG C/min, and natural cooling obtains body phase g-C3N4,
The body phase g-C that will be obtained3N4It is immersed in 0.5M-2M salpeter solution, stirs 20 ~ 50 minutes, it is then ultrasonic 20 ~ 50 minutes, then
Centrifugation, cleaning for several times, until pH value of solution be 7, obtain g-C3N4Nanometer sheet, the g-C that will be obtained3N4Nanometer sheet and TiO2It is dissolved into
In ionized water, TiO is formed2/g-C3N4Suspension, described g-C3N4Nanometer sheet and TiO2Mass ratio be 1：0.2 ~ 0.4, centrifugation
Cleaning, the finally high-temperature calcination at a temperature of 400 DEG C -600 DEG C, calcine TiO2/g-C3N4Mixture heating rate is in 2 DEG C/min-
10 DEG C/min, the adjustable titania modified graphite phase carbon nitride photochemical catalyst of dimension is made between 1h-4h in calcination time
（TiO2/g-C3N4Heterojunction photocatalyst）.
Further, described g-C3N4Presoma is any one in urea, thiocarbamide, dicyandiamide or melamine.
Further, described titanium dioxide is model P25 commercial titanium dioxide.
The present invention is first to body phase g-C3N4Acid treatment is carried out, by body phase g-C3N4Chemical stripping is into g-C3N4Nanometer sheet, complete
Dimension is adjusted.Then by simple calcination method, by TiO2Uniform load is to g-C3N4Surface, form TiO2/g-C3N4Hetero-junctions light
Catalyst.
Due to the increase of specific surface area and the presence of hetero-junctions, photo-generate electron-hole pair can be efficiently separated so that TiO2/
g-C3N4Heterojunction photocatalysis material has very strong catalytic performance under visible light conditions.Overcome g-C3N4Specific surface area is small, amount
The shortcomings that sub- efficiency is low.Effectively photochemical catalytic oxidation power-plant flue gas Elemental Mercury, the lower demercuration efficiency of LED irradiation it can reach 70%
More than, solve the problems, such as mercury emissions.
Titania modified graphite phase carbon nitride photochemical catalyst obtained by the present invention can be used as power-plant flue gas photocatalytic-oxidation
Change catalyst.Test result indicates that during, it can be seen that carry the simulated flue gas of element mercury（Nitrogen air）Urged by light
The content of element mercury significantly reduces after change reactor, improves photocatalysis demercuration efficiency under visible ray.
The present invention compares with prior art, and its technological progress is significant.Technique of the invention is simple, cost is low.Utilize
Photochemical catalyst made from this method, micro titanium dichloride load is on graphite phase carbon nitride nanometer sheet surface, hence it is evident that improves graphite
The quantum efficiency of phase carbon nitride, can be in photochemical catalytic oxidation gas mercury under visible light conditions.
