If exposing 001 face, high activity face, and its special helical structure (very thin thickness) and there is good light induced electron-sky
The separating effect in cave pair, to have this advantage of good catalytic activity to the degradation of rhodamine B under visible light conditions.Below
The invention will be further described in conjunction with the embodiments.
1: one step hydrothermal synthesis BiOCl photocatalytic material of embodiment；The preparation method can be with are as follows:
(1) 80ml ethylene glycol solution is measured with 100ml graduated cylinder, being subsequently poured into volume is to stir in 150ml conical flask, is used
Liquid-transfering gun takes the 20wt% aqueous solution of the PDDA (molecular weight 400.000-500.000) of 6.4ml, instills in above-mentioned conical flask, after
It is continuous to be vigorously stirred, Bi (NO is then added thereto3)3 .5H2O, magnetic agitation 30min；
(2) above-mentioned mixed solution is transferred in 200 DEG C of oil bath, is heated to reflux 2h.
(3) it is cooled to room temperature to above-mentioned mixed solution, is centrifuged, washed, dry.It is centrifuged 15min with supercentrifuge,
It is washed with deionized water 3 times, 80 DEG C of drying 12h in vacuum oven.
Different precursor B i (NO3)3 .5H2The amount of O, the catalyst of formation be respectively labeled as BiOCl-nanosheet,
BiOCl-nanosheet-10, BiOCl-nanosheet-20, BiOCl-nanosheet-40, as shown in the table.
| BiOCl-nanosheet | 0.097g |
| BiOCl-nanosheet-10 | 0.97g |
| BiOCl-nanosheet-20 | 1.94g |
| BiOCl-nanosheet-40 | 3.88g |
Photocatalysis test is carried out to BiOCl novel photocatalysis material: being degraded by target of the rhodamine B solution of 10mg/L
Object takes 50mL target degradation product to be put into glass reactor, and container outer layer is using condensation water termostat, with 300W xenon lamp (optical filter
> 400nm) as light source, three each 20mg of sample (the BiOCl nanometer chip architecture of different precursor salts, document is added in visible light
Middle BiOCl nanometers of dish structure).Dark treatment 30min, reach adsorption-desorption balance, take respectively 1min, 2min, 3min, 4min,
A sample is taken at interval of 20min after 5min, 10min, sample carries out centrifugal treating, to be centrifuged under conditions of 10000r/min
10min takes supernatant liquor, using UV-8500 ultraviolet-visible spectrophotometer (UV-Vis) to rhodamine B concentration (C/C0)
Variation is mapped.
Test results are shown in figure 4, and Fig. 4 B is the BiOCl- formed in no catalyst and three kinds of different precursor salts
Nanosheet, BiOCl-nanosheet-10, BiOCl-nanosheet-40 and BiOCl nanometers of dish structure reported in the literature
The comparison diagram degraded to rhodamine B, it can be seen that the BiOCl-nanosheet-10 novel photocatalysis formed in the present invention
Material, in the C/C of 5min rhodamine B degradation0It is reduced to 0.17, and BiOCl-nanosheet and BiOCl-nanosheet-40
In the C/C of 5min rhodamine B degradation0It is reduced to 0.49 and 0.61, it can be seen that with precursor B i (NO3)3 .5H2O's adds
Enter, the trend reduced again is first increased to the degradation presentation of rhodamine B, is primarily due to Bi (NO3)3 .5H2The addition of O
To 10 times of initial amounts (0.97g), BiOCl changes to 720nm (BiOCl- from initial 1.2 μm of size (BiOCl-nanosheet)
Nanosheet-40), due to the reduction of size, the area for causing the BiOCl of unit mass to contact with reaction solution becomes larger, to lead
It causes catalytic activity to increase, but further increases Bi (NO3)3 .5H2The amount of O reaches 40 times of initial amounts (3.88g), such as Fig. 4 A institute
Show, the structure with Moire fringe disappears, and the thicker nanometer dish structure of thickness is formd, so so as to cause catalytic activity drop
It is low.So visible regulation precursor salt is most important to catalytic reaction activity influence, regulate and control Bi (NO3)3 .5H2O is in (0.097g-
It is 0.97g) best.Fig. 4 C is that BiOCl-nanosheet-10 reuses four response diagrams to rhodamine B degradation, it can be seen that
At 4 times repeatedly, rhodamine B degradation can be completed in 50min.Therefore this that semiconductor band gap is regulated and controled based on Moire fringe
BiOCl photocatalytic material is catalyzed simultaneously with the excellent characteristic in the absorption visible light for being conventionally synthesized BiOCl nano-micro structure
Stability is preferable, easy to industrialized production and popularization.
Embodiment 2: the BiOCl novel photocatalysis material that the different heating time is formed, specifically:
(1) 80ml ethylene glycol solution is measured, pours into 150ml conical flask, takes PDDA (the molecular weight 400.000- of 6.4ml
500.000) 20wt% aqueous solution, instills in above-mentioned conical flask, is vigorously stirred, and 0.097g Bi is then added thereto
(NO3)3 .5H2O, magnetic agitation 30min；
(2) above-mentioned mixed solution is transferred in 200 DEG C of oil bath, take different return time 10min, 20min, 30min,
The sample of 40min, 120min, 240min, are cooled to room temperature；
(3) sample is cooled to room temperature, is centrifuged, washing, vacuum oven are dry.It is centrifuged with supercentrifuge
15min is washed with deionized water 3 times, 80 DEG C of drying 12h in vacuum oven.The BiOCl for the differential responses time being prepared receives
Rice chip architecture is as shown in Fig. 3 B-G.
As can be seen from the figure as apparent change has occurred in the variation BiOCl nanometer sheet in reaction time, from initial
10min to 30min, which can be seen that, has gradually formed Moire fringe, while as the reaction time extends, Moire fringe ratio is gradually
Increasing, in 2h-4h close to saturation, can be seen that Moire fringe percentage gradually increases from Fig. 3 H, band-gap energy gradually decreases,
The most obvious from 10min to 30min, band gap effectively reduces the band gap of BiOCl semiconductor material from 3.29eV to 2.88eV
Energy.
