Embodiment 1

[0064] Step (1): Using a three-electrode system for CV scanning to prepare iron oxide modified conductive carbon cloth:

[0065] In a three-electrode system, Fe 2+ The precursor solution is used as the electrolyte, the conductive substrate is used as the working electrode, the titanium electrode is used as the counter electrode, and the Ag / AgCl electrode is used as the reference electrode; the specific steps are as follows:

[0066] Step (1-1): Take 200mL acetate buffer solution (the concentration of sodium acetate is 0.2mol / L) and configure 10mmol / L FeSO 4 solution, and adjust the pH of the solution to 7.0 with acetic acid to obtain Fe 2+ The precursor solution;

[0067] Step (1-2): the configured Fe 2+ The precursor solution was transferred to the beaker, the above-mentioned three-electrode system was installed, and connected to the electrochemical workstation.

[0068] Step (1-3): Set the CV scanning range of the workstation to 0.1-1.6V, the scanning speed to 50mV / s, an...

Embodiment 2

[0076] The difference from Example 1 is that in step (1), Cu 2+ The precursor solution was used to modify the conductive carbon cloth.

[0077] Cu 2+ The precursor solution is Cu(CH with a concentration of 10mmol / L 3 COO) 2 An acetate-buffered saline solution with a pH of 5.5.

[0078] The CV scanning range of the workstation is -1.0-0.4V, the scanning speed is 50mV / s, and the number of scanning circles is 50 circles.

Abstract

The invention discloses a method for reducing CO2 by virtue of a metal oxide modified biofilm electrode. The method comprises the following steps: (1) performing CV scanning to prepare a metal oxide modified conductive substrate by adopting a three-electrode system; (2) performing biofilm formation on the metal oxide modified conductive substrate to form a biofilm with anaerobic bacteria; (3) domesticating the biofilm under applied voltage to form an electroactive biofilm, and reducing CO2 by virtue of the electrode biofilm under the synergistic effect of an applied electric field. According to the method, an electrically catalyzed-modified electrode biofilm system is constructed by taking the metal oxide modified biofilm as a cathode material, and is used for reducing CO2; measurement results show that the reduction rate of CO2 is higher than 10 percent and the system is high in running stability.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a metal oxide modified electrode for biofilm reduction of CO 2 Methods. Background technique [0002] The combustion of fossil fuels such as oil and coal produces a large amount of CO 2 emissions, leading to the "greenhouse effect". CO 2 The chemical properties are very stable, close to "inert gas". Therefore, looking for an efficient way to store and restore CO 2 has always been the focus of social attention. CO 2 The treatment technology of gas can be generally divided into two categories: separation and fixation from the atmosphere and separation and recovery from the discharge gas. At present, the technologies for separating and fixing carbon dioxide from the atmosphere mainly include biological methods, while the technologies for separating and recovering carbon dioxide from blow-off gas mainly include physical methods, chemical methods, and physical-chemical...
