Platinum Wire Ring Counter Electrode Φ0.5*230mm

Platinum is an inert metal and does not participate in the electrode reaction itself, so it is the first choice for the counter electrode. One of the important parameters of the counter electrode is its surface area. The counter electrode must have a large enough area to support the current conduction generated on the working electrode. Platinum electrodes include platinum sheet electrodes, platinum wire electrodes, and platinum mesh electrodes.

The platinum wire electrode has a relatively small area ，which is suitable for use in combination with a disc-shaped working electrode. The platinum wire electrode has a variety of shapes and structures, which can be bent according to the length of the platinum wire to be used with various types of electrochemical cells. The insulating rod material of the platinum wire electrode can be PTFE or PEEK rod.

As the working electrode undergoes an oxidation or reduction reaction, a gas evolution reaction or a reverse reaction of the working electrode reaction may occur on the counter electrode. Therefore, in some cases it is necessary to separate the working electrode from the counter electrode. The best way to reduce the interference of the reaction on the counter electrode on the working electrode is to use sintered glass, porous ceramics or ion exchange membranes to isolate the solution in the two electrode regions.

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...

H-Type In-Situ Raman Spectroscopy Cell With Double Light Window 30ml

In-situ Raman spectroscopy electrochemical cell is designed and manufactured for studying the in-situ spectra and morphology changes of electrode materials in electrochemical experiments. The working electrode is placed directly under the see-through window, so that the optical instrument can detect the working electrode from the quartz light window above the cell body. Commonly used instruments include optical microscopes, infrared microscopes, X-ray spectrometers, confocal Raman spectrometers, etc. According to different experimental test requirements, the in-situ Raman spectroscopy electrochemical cell is divided into four types: Single cell body with single light window type Single cell body with double light window type H type double cell body with single side light window type H type double cell body with double side light window type H-type double cell body with double-side light window type is an in-situ Raman characterization cell in which the working electrode and the c...

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...
