The oriented growth nanogold bacteria cellulose/carbon pipe composite membrane prepared is detected, it is as a result as follows：
As shown in Figure 1, Fig. 1 (a) shows that carbon nanotube and nano Au particle distribution are relatively uniform, carbon nanotube is tightly wrapped
It is rolled in the bacteria cellulose with ultra micro gap structure, while passing through distribution of the gold nanoparticle on BC/MWCNTs carrier,
Also explanation achieves preferable effect using the fixed carbon nanotube of suction method and in the fixed nanogold of composite film surface.By (b)
Figure is as it can be seen that bacteria cellulose shows the tridimensional network of random orientation, and surface pore is not of uniform size, elongated carbon nanotube
Be filled between the fiber gap of bacteria cellulose at random, a large amount of Au by uniform adsorption in composite film surface, to improve electrochemistry spirit
Quick property provides necessary condition.
As shown in Fig. 2, in the stretching vibration region of C-O, 1659cm-1And 1061cm-1Absorption peak to respectively correspond C-O non-
Symmetrical stretching vibration and pyranose ring skeletal vibration, 2973cm-1Place is the 3465cm as caused by the vibration of-CH--1Place be by-
Caused by OH group symmetrical stretching vibration.As seen from the figure, after multi-walled carbon nanotube being added, spectrogram peak is in 2973cm-1Locate micro-
Amount enhancing, in 3465cm-1Place is remarkably reinforced, this is because the addition of multi-walled carbon nanotube is so that flexible caused by the superposition of-CH- key
Vibration enhancing, while a large amount of-OH groups are introduced, illustrate there was only Physical interaction between BC and multi-walled carbon nanotube；Load is received
Meter Jin Hou, each wave crest is without significant change, then supported nano-gold particle does not generate BC/MWCNTs film items chemical property substantially
It influences.
As shown in figure 3, the ingredient of BC is cellulose, its thermal decomposition occurs in 220~400 DEG C of temperature ranges, this single order
The mass loss rate of section sample is up to 75%；It can see BC there are two apparent weightless peak from DTG curve, respectively correspond 220~
270 DEG C of temperature sections and 300~400 DEG C of temperature sections, caused by the two weightless peaks are all BC thermal decomposition.Wherein 300~400 DEG C it is right
The weightless peak-to-peak value answered is larger, illustrates that BC mass loss is very fast in this stage, and when temperature is 320 DEG C or so, BC heat point
Solution rate reaches maximum.The thermal decomposition of BC/MWCNTs film occurs in 350~400 DEG C of temperature ranges, the quality of this stage sample
Loss late about 50%；Can see BC/MWCNTs from DTG curve has an apparent weightless peak, corresponding 350~400 DEG C of temperature
Section.The thermal decomposition of BC/MWCNTs/Au NPs film occurred in 190~250 DEG C and 350~400 DEG C of temperature ranges, the first and second stage
The mass loss rate of sample respectively may be about 5% and 20%；DTG curve shows that first stage weightless peak is smaller, and mass loss is slower,
First stage is the main mass loss stage.
Comparison can obtain, and compare pure BC film, and the beginning weightless temperature of BC/MWCNTs film improves about 100 DEG C, and percent weight loss reduces
About 25%；BC/MWCNTs/Au NPs film beginning weightless temperature then reduces about 30 DEG C, but main weightless temperature improves about 50 DEG C, and loses
Weight percentage substantially reduces.It to sum up states, BC film thermal stability after processing improves.
As shown in figure 4, comparing pure BC film, the diffraction of the bacteria cellulose of BC/MWCNTs and BC/MWCNTs/Au NPs film
Peak heights increase, and diffracted intensity significantly improves, then the crystallization degree of bacteria cellulose film after processing increases；Meanwhile in BC/
On MWCNTs and BC/MWCNTs/Au NPs film, there is peak at (004) in C (002), C (100), C (101), C, it was demonstrated that carbon is received
Mitron bacteria cellulose film adsorption in order.Compared to BC/CNT film, the film after loading nanometer Au particle is in Au
(111), there is peak at (220) in Au (200), Au, illustrate absorption of nanometer Au on film in order.
As shown in figure 5, it can be observed that apparent anode and cathode peak point current, and with the increase of sweep speed, electricity
The peak value of stream is positive respectively, inversely increases, and the AuNPs and BC/MWCNTs that this explanation is connect with electrode surface on BC can be into
The transfer of row laccase redox reaction electronics.As shown in Figure 5 B, using anode peak and cathodic peak current as in 50-350mV model
Enclose the subduplicate function of interior sweep speed, it is seen that with the raising for sweeping speed, linear increase is presented in peak point current.The result shows that
The electrochemical reaction on laccase electrode surface has controllability, for stable electrochemical system.
As shown in fig. 6, in fig. 6, it has also been observed that apparent anode and cathode peak point current, sweep speed by
50mV increases to 300mV, and anode peak current is gradually increased to about 0.7mA by 0.2mA, cathodic peak current value by -0.2mA gradually
About -0.83mA is increased to, illustrates to couple between glucose oxidase and BC/MWCNTs/AuNPs bioelectrode good.Such as Fig. 6 B
It is shown, it is same to advise using anode peak and cathodic peak current as the subduplicate function of the sweep speed within the scope of 50-350mV
Rule, with the raising for sweeping speed, linear increase is presented in peak point current.The result shows that glucose oxidase is modified BC/MWCNTs/
The chemical reaction of AuNPs electrode surface has controllability.
