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 electrode, and sometimes auxiliary electrode), an electrolyte solution, and a cell housing or chamber.

Raman spectrometer: The spectrometer is used to generate Raman spectra by shining laser light onto the sample and analyzing the scattered light. In an in situ setup, the spectrometer is often coupled with the electrochemical cell, allowing for simultaneous Raman measurements during electrochemical experiments.

Optical components: Optical fibers or other components are used to direct the laser light to the sample and collect the scattered light for analysis.

Electrochemical control system: This system regulates the applied potential or current to the working electrode, allowing researchers to control the electrochemical conditions during the experiment.

By combining electrochemical techniques with Raman spectroscopy, researchers can gain valuable insights into various electrochemical processes, including electrodeposition, battery charging and discharging, corrosion, fuel cell reactions, and electrocatalysis. This approach has applications in materials science, catalysis, energy storage, and environmental science, among other fields.

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 Reference Electrode?

According to the test requirements, you can use the following content as a reference for selecting reference electrode. Different research systems can choose different reference electrodes: Neutral system: saturated calomel electrode or Ag/AgCl reference electrode Alkaline system: Hg/HgO reference electrode Acidic system: Hg/Hg2SO4 reference electrode Non-aqueous system: Non aqueous Ag+ reference electrode Compared with other reference electrodes, Ag/AgCl reference electrode is more sensitive to light.At the same time, the silver chloride electrode is also less affected by temperature than other types of reference electrode. If you choose calomel electrode, Hg2/HgSO4 electrode or Hg/HgO electrode, you can add a salt bridge under the electrode to protect the reference electrode and minimize the potential affected by temperature. Mercury Oxide Reference Electrode Hg/HgO PTFE Rod 6 * 60 mm is a good choice for the Alkaline system. you can find all the reference electrodes from ...

Ag AgCl Reference Electrode Silver Silver Chloride Φ6*140mm Glass Rod

In electrochemistry, in order for a specific reaction to occur, a stable electric potential needs to be applied to the working electrode. The potential of the working electrode should always be accurately controlled. This is why a reference electrode is needed as a potential reference standard. Common reference electrodes include Silver Silver Chloride Ag/AgCl reference electrode, saturated calomel electrode,Hg/HgO reference electrode, Hg/Hg2SO4 reference electrode and Non aqueous Ag+ reference electrode,etc. The silver-silver chloride (Ag/AgCl) electrode is the most commonly used reference electrode. Compared with calomel electrodes that use mercury and its salts, Ag/AgCl electrodes are more environmentally friendly. Its electrode potential also has sufficient stability, reliability and reproducibility. Special attention should be paid to maintenance and storage when using Ag/AgCl reference electrode. Before use rinse it with deionized water. If air bubbles are present around the poro...
