Colourity is bigger, it is possible to absorb light, reduces the transparency of water body, causes anoxia in water, very big to microbiological effect in water body,
Destroy the self-purification of water；Secondly, dyestuff is raw after organic aromatic compound benzene ring hydrogen is replaced by halogen, nitro, amido
Many phenyl ring substituted compounds such as the aromatic halide of one-tenth, aromatic nitro compound, aromatic amine chemicals, biphenyl, poison
Property the biggest, the harm that can produce " teratogenesis, carcinogenic, mutagenesis " that has, in waste water, content of organics is high, complicated component,
Harmful substance contents is high.Due to the bio-refractory of waste water from dyestuff, semi-conducting material photocatalysis oxidation technique is closed increasingly
Note, it has also become study hotspot both domestic and external.Recently coming, bismuth system catalysis material gets more and more people's extensive concerning, as one
Important BiOX, BiOCl is a kind of novel polynary bismuth metal oxide photocatalyst, due to its suitable forbidden band width
Degree, special layer structure and there is good photocatalytic activity and enjoy pass, but, the photocatalytic of a kind of semi-conducting material
Can be not only relevant with the optical property of photocatalyst, important relation is also had with light source.Generally, urge higher than light when photon energy
During the energy gap of agent, the preferable photocatalysis effect of photocatalyst competence exertion, illumination is the strongest, and photocatalysis performance is the best.Carry
The photocatalysis effect of high photocatalyst can be in terms of the character two of the utilization rate and change catalysis material that improve nature light
Consider.
Graphene be a kind of energy gap be the semimetal of zero, in photocatalysis field, due to Graphene, to have the electronics of uniqueness special
Property, great specific surface area and higher transparency become the ideal carrier of synthesis composite photo-catalyst, the electricity of Graphene
Transport factor is the highest, utilizes Graphene to be modified photocatalyst, not only can realize broadband light and absorb, but also
Electric charge can be made more to mate with catalyst in transfer process, improve its photocatalysis performance；Next to that Graphene has uniqueness
Two-dimensional surface structure and there is bigger specific surface area, can induce when forming complex to produce and the strong absorption of pollutant is made
With, beneficially the carrying out further of photocatalytic degradation.
Summary of the invention
Present invention solves the technical problem that there is provided one can the stannum of effective rhodamine B degradation (RhB) waste water from dyestuff
The preparation method of the bismuth oxychloride/graphene composite photocatalyst of doping.
The present invention solves that above-mentioned technical problem adopts the following technical scheme that, the bismuth oxychloride/stone of a kind of tin dope
The preparation method of ink alkene composite photo-catalyst, it is characterised in that concretely comprise the following steps: (1) is by 1mmol Bi (NO3)3·5H2O dissolves
Obtained solution X in the hydrochloric acid solution that 10mL molar concentration is 1mol/L；(2) by 1mmol SnCl2·2H2O agitating heating is dissolved
Transparent settled solution Y is obtained in the hydrochloric acid solution that 40mL molar concentration is 1mol/L；(3) under stirring, by solution X by
Instill in solution Y, after continuing stirring 30min, regulate the pH of mixed solution with the sodium hydroxide solution that molar concentration is 2mol/L
Value is 6；(4) continuing stirring 2h after the pH value of complete mixed solution to be regulated, sucking filtration is precipitated thing, respectively washes three with water and ethanol
Secondary, in thermostatic drying chamber, the bismuth oxychloride visible light catalyst of tin dope is then prepared in 60 DEG C of dry 5h；(5) by 0.625-
Obtaining the aqueous solution of Graphene in the 5mg graphene oxide ultrasonic 50mL of being dissolved in water, the bismuth oxychloride adding 1g tin dope is visible
Photocatalyst, ultrasonic disperse 30min, it is stirred for 2h, sucking filtration is precipitated thing, respectively washes three times with water and ethanol, then at constant temperature
Drying baker prepares the bismuth oxychloride/graphene composite photocatalyst of tin dope in 60 DEG C of dry 5h.
Further preferably, in step (5), the addition of graphene oxide is preferably 2.5mg, and the stannum prepared under the conditions of being somebody's turn to do is mixed
The rhodamine B of degraded rhdamine B waste water 3h under natural sunlight goes miscellaneous bismuth oxychloride/graphene composite photocatalyst
Except rate is 99.91%.
The bismuth oxychloride of the tin dope that the present invention prepares/Graphene composite visible light catalyst has preferable light absorption
Can, and there is visible light-responded photocatalysis performance, there is under sunlight the property of efficient degradation rhdamine B waste water
Can, absorption spectrum ranges width, stable performance, nontoxic and cost effective, it is possible to be applied to the fall of difficult for biological degradation organic pollution
Solve, there is stronger market application foreground.
