Observable CO2RR Gas Diffusion Flow Cell

 


Electrocatalytic reduction of CO2 can store renewable energy in the form of chemical raw materials and high-value chemicals, which is one of the important methods to solve energy problems.  Most researches on CO2 electroreduction use H-type electrolytic cell, but the mass transfer in H-type electrolytic cell severely limits the reaction rate, that is, the current density. The flow electrolytic cell not only breaks through the mass transfer limitation of the H-type cell, and enables the CO2 reduction current density to reach the industrial level. At the same time, it can also use a high pH electrolyte to inhibit the hydrogen evolution reaction.


Characteristic:

1. Compared with the usual H-type electrolytic cell, the liquid flow electrolytic cell has more advantages in liquid phase mass transfer kinetics.

2. Directly supply CO2 gas to the cathode, which overcomes the disadvantages of low solubility and slow diffusion of CO2 gas in aqueous solution.

3.The thickness of the electrode plate can be customized according to the needs, which can effectively shorten the distance between the anode and the anode, reduce the resistance, and improve the test efficiency.

What is the CO2RR Gas Diffusion Flow Cell?

The CO2RR Gas Diffusion Flow Cell (CO2RR GDFC) is a type of electrochemical cell used in the conversion of carbon dioxide (CO2) to other chemicals through a process called the CO2 reduction reaction (CO2RR). It is similar in design to the Gas Diffusion Flow Cell (GDFC) used to measure gas permeability, but it is specifically designed to facilitate the electrochemical reduction of CO2. The CO2RR GDFC consists of a small, sealed chamber with two compartments separated by a thin, gas-permeable membrane. One compartment is filled with a CO2-containing gas mixture, while the other compartment contains an electrolyte solution and a catalyst material, such as copper or silver, which facilitates the CO2RR. The two compartments are separated by the gas-permeable membrane, which allows CO2 to diffuse from the high concentration compartment to the low concentration compartment. The CO2RR is driven by an electric potential applied across the two compartments, which induces the reduction of CO2 int...

How to choose the size of Reference Electrode?

 How to choose the size of Reference Electrode? The diameter of   ERA131B [ Silver Silver Chloride Ag/AgCl Reference Electrode Φ4*50mm Glass Rod ]   glass tube is 4mm, which is not the best choice for CHR221B2. The diameter of   ERA131A [ Silver Silver Chloride Ag/AgCl Reference Electrode Φ6*70mm Glass Rod ] is 6mm, which is more suitable for CHR221B2.     L et me   briefly introduce this electrochemical cell for you.I attached two images, so you can see it clearly: Figure 1   is the default opening diagram of   CHR221B2 [ H-Type Sealed Electrochemical Cell 30ml 45ml ] .   The left side is the working electrode chamber opening diagram, and the right side is the counter electrode chamber opening diagram. As shown in the parameter diagram on our product details page, we place the working electrode and the reference electrode in a chamber, and are equipped with gas inlet and outlet holes [for inert gas protection and oxygen-free o...

In Situ Raman Electrochemical Cell

In Situ Raman Electrochemical Cell is a specialized setup used in Raman spectroscopy to study chemical reactions and processes that occur at electrode surfaces under electrochemical conditions. Raman spectroscopy is a technique used to analyze the vibrational modes of molecules, providing information about molecular structure, composition, and interactions.   In an in situ Raman electrochemical cell, the setup integrates a Raman spectrometer with an electrochemical cell, allowing researchers to monitor changes in molecular composition and structure in real-time as electrochemical reactions take place at the electrode surface. This setup enables detailed insights into the mechanisms of electrochemical reactions, the formation of reaction intermediates, and the behavior of catalysts or electrode materials under working conditions. Key components of an in situ Raman electrochemical cell typically include: Electrochemical cell: This includes electrodes (working electrode, reference ele...
