Embodiment is as follows:
Graphene gas-diffusion electrode (GDE) has loose structure, and thickness of electrode is smaller, is conducive to gas to pass through micropore
Transmission of the structure from solution to electrode surface.Graphene gas-diffusion electrode substrate of the present invention is iron skeleton, by iron internalization to electricity
It is extremely internal, applied to can both improve its oxidation efficiency in electricity-Fenton-like system, cost is reduced again, while can overcome
Fe2+It can not reuse and the problems such as poor processing effect, can be met to having under electricity-treating organic waste water by Fenton method neutrallty condition
The degraded of machine thing waste water.
Embodiment one：
A kind of preparation of Fe skeletons-graphene gas-diffusion electrode：
Powdered Activated Carbon, deionized water and absolute ethyl alcohol are mixed in 1g: 100mL: 10mL ratio, and 0.05g is made
Hole agent NH4HCO3Incorporation wherein, then is sufficiently stirred for being allowed to uniform, then by gained mixed liquor and PTFE that mass fraction is 10%
Emulsion is sufficiently mixed for 80: 1 ratio in mass ratio, then is well mixed it through supersonic oscillations.A period of time is placed, this is treated
Mixture is attached in a length of 1cm, a width of 0.7cm iron net when being in sticky pasty state, and is pressed on hydraulic press thickness
Spend the gas-diffusion electrode for 0.6mm.Before use, electrode need to soak 24h in fresh acetone, to remove the second of its remained on surface
Surface reactive material in alcohol and PTFE, is finally rinsed and dried repeatedly with deionized water.
A Fe skeletons-graphene gas-diffusion electrode prepared is with being not added with Graphene electrodes and nickel screen by the following examples
Electrode is compared, and has carried out the experiment of electrochemical gaging, compares LSV the and CV curves of three, description of test is in iron net electrode
On can not only occur reversible redox reaction, and be conducive to the degraded to organic wastewater：
As shown in figure 1, iron net electrode, nickel screen electrode and be not added with Graphene electrodes -1V or so be in crest the reason for be by
In addition voltage change speed quickly, when reach deoxidation agent decomposition voltage when, the material is reduced rapidly on electrode, production
Give birth to very big electric current.Because oxidant is reduced rapidly on electrode, its concentration near electrode is drastically reduced, thickness is spread
Degree increase, and the oxidant in solution main body has little time to be diffused into electrode, thus electric current declines rapidly, when electrode reaction speed with
When diffusion velocity reaches balance, electric current would not change again, form crest electric current.And three compares iron net electrode and nickel screen electrode
Because being reversible electrode there is crest electric current, but it is the electrode for being not added with graphene for irreversible electrode, due to electrode
Reaction speed is slow, and in quick scanning, electrode reaction speed does not catch up with oxidation rate, and volt-ampere curve will occur without electric current.
As shown in Fig. 2 iron net electrode two oxidation peaks occurs in -0.75V and -0.85V or so, it is not added with Graphene electrodes and does not have
Occur oxidation peak and illustrate that its redox property is bad.There is reduction peak, iron net in -1.2V or so in negative sense scanning nickel screen electrode
There is reduction peak in -0.85V or so in electrode, and is not added with Graphene electrodes also without there is peak value.It is indicated above that iron net electrode
On can occur redox reaction because curve closure product existence is more stable.Because there is multigroup oxidation in it
Peak, so the redox property in rhodamine B is preferably, degradation effect is best.
Embodiment two：
This experiment simulates degrading waste water using rhodamine B, and the solution configured is moved into 50mL beakers, using titanium plate as sun
Pole, respectively with nickel screen graphene gas-diffusion electrode, be not added with product made from the gas-diffusion electrode and the present embodiment of graphene
Degradation experiment is carried out for negative electrode, anode and cathode effective area is 0.7cm2(the long wide 0.7cm of 1cm).Rhodamine B concentration is 10mg/
L, processing volume is 50mL, and reaction time 60min, current density is 20mA/cm2, electrolyte (NaSO4) concentration be 0.05mol/
L, electrode spacing 1cm, initial pH=3.0, whole process aeration.Gas-diffusion electrode degradation efficiency obtained above is measured.
As a result show：Self-control Fe skeletons-graphene gas-diffusion electrode does negative electrode, degradation efficiency highest.
Below by way of product made from nickel screen graphene gas-diffusion electrode, gas-diffusion electrode, carbon plate and embodiment one
Degradation experiment is carried out, compares four degradation efficiency：As shown in figure 3, during rhodamine B degradation, loading the negative electrode of graphene
The degradation efficiency of material degradation rhodamine B is higher than the cathode material and carbon plate of unsupported graphene, so as to embody graphene gas
The superiority of diffusion electrode；In the iron net electrode and nickel screen electrode that have loaded graphene simultaneously, the final degradation effect of iron net is more
It is good.
As shown in figure 4, product made from embodiment one is used as cathode material rhodamine B degradation, in pH=7, degradation rate
Still have 89.53%, illustrate Fe skeletons-graphene gas-diffusion electrode applied to degradable organic pollutant in electricity-Fenton-like system not
The good degrading effect only in pH=3, still there is higher degradation rate in neutral conditions.
, need not be again in degradation experiment because Fe skeletons-graphene gas-diffusion electrode is using iron net as substrate in this experiment
Additional iron ion, while on electricity-Fenton-like system negative electrode, Fe3+Electronics can be obtained and be converted into Fe2+, continue to participate in after electricity-Fenton
Continuous reaction, therefore compared to nickel screen graphene gas-diffusion electrode, Fe skeletons-graphene gas-diffusion electrode as negative electrode electricity-
The generation of iron cement can be prevented effectively from Fenton-like system.
