Description
Technical field
The present invention relates to nano material and photocatalysis degradation organic contaminant technical field, particularly relate to one kind
The preparation method and application of Fe-BiOCl photochemical catalyst.
Background technology
Since in recent years, global environmental pollution and problem of energy crisis are increasingly severe, increasing trade waste, life
The organic pollutions such as rubbish of living enter in water body for the survival of mankind, and Photocatalyst is then to solve organic pollution
Problem provide a green, reliable approach.Therefore, exploitation practicality and high efficiency pollutant abatement technology become facing mankind and
Letter significant problem to be solved.Bismoclite is a kind of Inorganic synthese material, has notable in terms of administering organic pollutants
Effect, but bismoclite material has larger energy gap, can only absorb the low ultraviolet light of comparision contents in sunshine
Competence exertion acts on, the method that this patent adopts Metal Ions Modification, and bismoclite is modified.By bismoclite photocatalysis
The response wave length of material diffuses to the scope of visible ray.
Content of the invention
Meaning of the present invention be for existing issue provide a kind of quickly, simply prepare visible light-responded
Fe-BiOCl catalysis material.The composite that the method is obtained has preferable photocatalysis performance.
The present invention does not use precious metal raw material, low cost and the method process simple it is easy to operation, can be used for large quantities of
Amount produces the composite that the method is obtained, and has broad prospect of application in fields such as sewage disposals.
The Fe-BiOCl catalysis material preparation method that the present invention provides is as follows：
A certain amount of bismuth nitrate is dissolved in wiring solution-forming 1 in 30mL ethylene glycol；A certain amount of iron chloride is dissolved in 30mL second
Wiring solution-forming 2 in glycol；A certain amount of hexadecyltrimethylammonium chloride (CTAC) is dissolved in wiring solution-forming in 30mL ethylene glycol
3.Then solution 2 is slowly dropped in solution 1, after continuing stirring a period of time, then solution 3 is added drop-wise in solution 1, continues
Put into 10 minutes in microwave reactor after stirring 30min, power setting is 200W.The pelleting centrifugation that will produce, successively with distillation
Water and absolute ethanol washing, then 60 DEG C of vacuum drying obtain corresponding Fe-BiOCl catalysis material.
Under visible radiation, the photocatalytic activity test concrete grammar of rhodamine B degradation and condition are as follows：
The Photocatalytic oxidation activity of catalyst is to carry out in homemade photo catalysis reactor.Under normal temperature and pressure, adopt
300W xenon lamp lamp is radiating light source, and reactant liquor is the rhodamine B solution of 200mL 20mg/L, and catalyst charge is 0.2g,
Reactor bottom fills into oxygen.Extract a small amount of reactant liquor every 5min under violent stirring, measure solution extinction at 554nm
