MoS2、 g-C3N4And CNTs.
As shown in Fig. 2 all CNTs characteristic peak (3450cm-1、1634cm-1、1375cm-1、1100cm-1) and g-
C3N4Characteristic peak (3168cm-1、1635cm-1、1574cm-1、1420cm-1、1328cm-1、1238cm-1、812cm-1) can
From MoS2/CNTs/g-C3N4It is observed that explanation g-C in collection of illustrative plates3N4With CNTs successful load.
As shown in figure 3, pure molybdenum sulfide absorbs weaker in visible-range.MoS2/g-C3N4In the wavelength less than 500nm
Scope produces strong absorb.MoS2/g-C3N4Compared with MoS2/ CNTs shows stronger absorbability in visible region. MoS2/
CNTs/g-C3N4The absorbability shown in visible-range is weaker than MoS2/g-C3N4But it is better than MoS2/ CNTs, it is known that right
The raising of visible absorption ability is essentially from g-C3N4Rather than CNTs.g-C3N4Catalysis material is improved to visible ray
Absorbability, so as to improve the utilization rate of solar energy.
As shown in figure 4, C 1s two peaks are respectively in 283.1eV (C-C) and 287.6eV (N-C=N).287.6eV with
288.0 eV, which are close, understands CNTs to g-C3N4N-C=N have little to no effect.N 1s peak appears in 298.3eV (C=N-
C).Mo 3d peak understands that the existence form of molybdenum is Mo in 227.6eV and 230.6eV respectively4+, S 2p peak is respectively appeared in
Existence form knowable to 160.2 eV and 161.6eV is S2 2-。
As shown in figure 5, prepared MoS2/CNTs/g-C3N4The TEM photos of sample, its pattern is sheet, and its edge can
To be clearly visible that CNT is compounded on sample.
As shown in fig. 6, the crystal striped distance respectively 0.366nm and 0.63nm measured, corresponds to g-C respectively3N4
And MoS (002)2(002) interplanar distance.It can be seen that g-C3N4And MoS2Successfully it is combined together.
Photocatalytic activity is tested：
The photocatalysis performance of prepared sample is evaluated using Rh B as model compound.In an experiment, exist
100mL 0.01mmolL-1Rh B solutions in add and 0.01g catalyst and be put into glass reactor.Using 500W xenon lamps (λ
＞ 420nm) irradiation.420nn wave filters are inserted between lamp and sample to remove ultraviolet light (λ ＜ 420nm).Shone in visible ray
By suspension strong agitation 15 minutes in the dark before bright.Then solution is exposed to radiation of visible light under magnetic stirring.
In given time interval, periodic collection and analysis 4mL suspension.Rh B concentration is entered by UV-2550 ultraviolet spectrometers
Row analysis, absorption spectrum intensity is recorded when the maximum wave band of ultraviolet-visible is 552nm.
As shown in fig. 7, prepared MoS2/CNTs/g-C3N4Compared with pure phase MoS2、C60、g-C3N4、MoS2/CNTs、 MoS2/
g-C3N4And CNTs/g-C3N4Photocatalysis efficiency is improved largely, wherein 9%MoS2/C60/g-C3N4Rhodamine B photocatalysis is imitated
Rate highest, through radiation of visible light 25min rhodamine B degradation rates up to 100%.
