Is there anyone doing electrochemical reduction of carbon dioxide, I would like to ask for advice

1) CO2+CO32-+H2O=2HCO3-(2)K2CO3(3)CD(4)CL-(5)2mNO2+2E-+H2O=2OH-+Mn2O3 Colorless gas and white precipitation produce test question analysis: (1) The absorption of CO2 in K2CO3 solution generates KhCO3, and the K+ deletion is written as an ion equation. (2) K2CO3 is obtained by thermal decomposition of K2CO3, which is a circular substance; (3) The reaction reaches an equilibrium state and two more characteristics:

One is v (positive) = v (inverse); Second, the content of each substance component remains unchanged. aThe image does not illustrate the rate of the reverse reaction and cannot be determined; b is the constant k that the reaction is equilibrized, which has nothing to do with whether the reaction reaches equilibrium, it is related to temperature, and b cannot judge whether it is equilibrium or not; The amount of CH3OH and CO2 in C does not change, that is, the components do not change, indicating that the equilibrium state is obtained; D is the content fraction of H2 is unchanged, and the component is constant, indicating that the equilibrium state is obtained. (4), when the precipitation is started, c(ag+)==; c(ag+)== at the beginning of precipitation.

Therefore, Cl- precipitates first. (5) The oxidant mnO2 is used as a cathode material to obtain electrons and generate Mn2O3, and pay attention to the environment, so OH- is generated. Electrolytic (inert electrode) a sufficient amount of Mg(NO3)2 and NaCl mixed solution, according to the discharge sequence, the anode Cl- discharge, cathode water ionized H+ discharge, to produce OH, combined with Mg2+ to form MG(OH)2 white precipitate.

SP calculation and electrochemical reaction principle.

I do electrochemical ethanol oxidation, so we can learn and communicate together

An appropriate catalyst can reduce the activation energy of the CO2 reaction, and the activation energy of the CO2 counter-accompaniment can reduce the high selectivity and current efficiency of the reed sliding pin. Suitable catalyst materials play a crucial role in the electrochemical reduction of CO2.

Generally, the rotating disc electrode test is not sealed. Unless you buy a unit that comes with a sealed design, it is difficult to retrofit it to a sealed one. If the sealing at the shaft does not affect the uniformity of rotation, manual modification is very difficult, and it is easy to injure the equipment.

However, it is also possible to seal the entire device.

Normally, the test gas is passed into the liquid level and the test can be done. If you're just afraid that the restored CO is toxic, just put the whole unit in a fume hood. In addition, the general reduced current is at the milliampere or microampere level, and the amount of CO restored is very small, and there is not as much CO as the cigarette produced by roadside people, and it will hardly cause much harm to the human body.

Potassium bicarbonate. Colorless transparent monoclinic crystal structure. relative density, stable in air.

Soluble in water, it is weakly alkaline due to hydrolysis. The aqueous solution and magnesium salts do not precipitate basic salts. Insoluble in alcohol.

It starts to decompose at 100 hours and completely decomposes at 200 hours, losing carbon dioxide.

and water into potassium carbonate.

Based on the above properties of potassium bicarbonate, we use it in the electrochemical reduction of CO2.

mass transport

Interpretation] mass transport; mass transportation; collective transport; water transfer;

network] bulk transportation; material transport; mass migration;

Example sentence] due to unstability of o2 fluid and slow mass transport, red pbo inclusions are easily formed in the crystal

Due to the unstable airflow and the slow mass transport, some red PBO wraps tend to form inside the crystal.

Good hair, in the final analysis, are you just making electrode materials, and can you make a little new material?

A novel tin electrode was prepared by hydrogen bubble dynamic template method for tin deposition on copper substrates. SEM, EDS and XRD were used to characterize the porous tin deposits, and their catalytic performance of CO2 electrochemical reduction to formic acid was studied.
