Detailed Description
The technical solutions of the present invention are further described below with reference to examples, but the present invention is not limited to the contents of the examples in any way. In the examples, unless otherwise specified, the experimental methods are all conventional methods; unless otherwise indicated, the experimental reagents and materials were commercially available.
EXAMPLE 1 preparation of NiNPs/AuNPs/MFC electrodes
(4) MFC processing
And taking a piece of MFC for standby, ultrasonically cleaning MFC glass for 30 minutes by using deionized water, taking out, washing by using the deionized water, and drying by using nitrogen for standby.
(2) Flower-like nano gold deposition
Using a three-electrode system, with MFC electrode immersionInto H2SO4(0.5M) and KAuCl4(1mg/m L) in the mixture, a platinum electrode was used as a counter electrode and Ag/Ag Cl as a reference electrode. Setting electrodeposition parameters of an electrochemical workstation by adopting square wave voltammetry: initial voltage-0.2V, end point potential: -0.9V, potential increment: 0.05V, amplitude 0.025V, frequency 20 HZ. And (5) carrying out nitrogen protection on the electrode after deposition, and standing for standby after three days.
(3) Preparation of Ni-Au/MFC composite electrode
A three-electrode system is adopted, AuNPs/MFC with a nano structure is used as a working electrode, an Ag/AgCl electrode and a platinum wire electrode are used as reference electrodes, and a counter electrode is placed in an electrolytic cell filled with nickel sulfate solution. Setting electrodeposition parameters of an electrochemical workstation by adopting a potentiostatic method: voltage-1V, time 300 s. And immediately taking out the electrode, washing the electrode with deionized water for multiple times, and standing the electrode for later use under the protection of nitrogen after deposition.
Based on the MFC/nano nickel-gold composite electrode surface topography as shown in figure 1, the nano-particle size and distribution on the electrode are uniform, and the electrocatalytic performance is particularly outstanding.
Example 2 comparison of cyclic voltammograms of maltose solution and blank solution
Firstly, placing a three-electrode system in a KOH solution with the pH of 14 and the concentration of 1mol/L, scanning within a potential range of-0.2-1.3V by using a cyclic voltammetry method, and recording a cyclic voltammetry curve of a blank solution; then, the three-electrode system is placed in 10mmol/L maltose solution to be detected containing 1mol/L KOH solution with pH of 14 as supporting electrolyte, and scanning is carried out in a potential range of-0.2-1.3V by using cyclic voltammetry, and the cyclic voltammetry curve of maltose is recorded. As shown in fig. 2: the catalytic effect of the Au-Ni electrode at 10mmol/L maltose was tested at a scan rate of 100 mV/s. From the figure, it can be seen that the Au-Ni electrode has a good catalytic activity for maltose. The fuel composed of the Ni-Au/MFC electrode can convert the biological energy into the electric energy with high efficiency.
Example 3 Cyclic voltammetric response of NiNPs/AuNPs/MFC electrodes to maltose of the same concentration at different sweep rates
Sequentially placing the three-electrode system in a 10mm maltose solution to be detected containing 1mol/L KOH solution with the pH value of 14 as a supporting electrolyte, testing the maltose solutions with different sweep rates at the same concentration, wherein the sweep rates are respectively 20m V/s, 40m V/s, 60m V/s, 80mV/s and 100m V/s, and scanning within a potential range of-0.2-1.3V by using a cyclic voltammetry. Cyclic voltammograms of maltose at the same concentration and different sweep rates were recorded. As shown in the attached figures 3 and 4: as can be seen from the figure, with the continuous increase of the sweep rate, the oxidation current of the nano electrode in the maltose solution is also continuously increased, the oxidation peak is also continuously increased, and a good linear response for catalyzing maltose is presented, so that the Au-Ni electrode can be proved to be used for catalyzing maltose to be diffusion control.
Example 4 NiNPs/AuNPs/MFC electrode anti-poisoning Curve
First, a three-electrode system was placed in a 10mm maltose test solution containing 1mol/L KOH solution having a pH of 14 as a supporting electrolyte, and a time-current curve of maltose was recorded at a potential of 0.6V by the time-current method. However, as shown in fig. 5, the current density drops sharply at the beginning. At the beginning of the reaction, it is a fast kinetic reaction, so the active site does not contain adsorbed maltose molecules. Thereafter, adsorption of the neomaltose molecules depends on the release of the electrode catalytic sites by oxidation of maltose, or the electrode catalytic active sites are occupied by intermediate species such as CO, CHx, etc. formed in the first few minutes (rate determining step). Therefore, the slight decrease in current density is mainly due to the poisoning of the catalyst. Furthermore, the specific current experienced a rapid drop during the first 300 seconds throughout the test and was still a smooth and gentle change after the end of the test, with a decay of about 9%.
The above description is only for the purpose of creating a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can substitute or change the technical solution and the inventive concept of the present invention within the technical scope of the present invention.
