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

The H-type double cell body with a single-side light window is a specialized in-situ Raman characterization cell that divides the working electrode and counter electrode into separate chambers. This cell is capable of performing Raman spectroscopy measurements on a variety of research materials, including during the CO2RR reaction process.

characteristic:

1.The main body of the in-situ Raman pool is made of polytetrafluoroethylene material, which is made by meticulous crafting.

2.The size of the working electrode chamber is 80*80*30mm, the internal electrolyte solution part is a space of φ55*13mm, and the volume is 30ml. The size of the counter electrode chamber is 80*30*30mm. The diameter of the intermediate ion membrane exchange channel is 14mm.

3.The Raman cell is equipped with JGS2 quartz plate, the size of the quartz plate is φ41*1mm. The spectral application range of JGS2 optical quartz glass is 220-2500nm.

4. In a Raman cell, the typical working electrode comprises a PEEK holder that can secure sheet materials like carbon paper, metal sheets, metal mesh, foamed nickel, and conductive glass. The distance between the material surface and the quartz sheet is roughly 5mm. However, there are also options for detachable L-shaped glassy carbon or gold disk electrodes that can reduce this distance to 0.5mm.

5.The standard counter electrode of the Raman cell is a platinum wire electrode, and the electrode size is φ0.5*37mm. There are also φ0.5*100mm or φ0.5*230mm platinum wire ring electrodes instead.

6.The standard reference electrode of the Raman cell is an Ag/AgCl reference electrode. There are also saturated calomel electrodes, Hg/HgO electrodes, Hg/Hg2SO4 electrodes and non-mercury Ag+ reference electrodes instead.

7. Within the working electrode chamber of the cell, both the working and reference electrodes can be accommodated. To facilitate air flow or electrolyte circulation, two small apertures are located on either side of the quartz light window. Meanwhile, the counter electrode is positioned in a separate chamber and features a small aperture at the top for anode gas production and discharge.

8.The Raman cell can be quickly assembled and disassembled, and it is easy to clean.
