In Situ Raman Spectroelectrochemical Cell (Disk Electrode), Model: EC-RM4

Description

Product Overview

The EC-RM4 is designed for in situ Raman characterization of electrode materials during electrochemical testing. The working electrode is positioned directly beneath a transparent optical window, enabling spectral acquisition during operation. Its PEEK and high-purity titanium construction supports flow-system testing and syringe-based electrolyte filling, while allowing rapid assembly, disassembly, and cleaning.

Key Features

• Short Optical Path: A WE-optical window distance of less than 3 mm supports Raman acquisition from the working electrode.
• Interchangeable Disk Electrodes: Supplied with a Ø5 mm glassy carbon electrode and compatible with optional Au, Pt, and Ag disk electrodes.
• Flexible Electrolyte Handling: Supports flow-system operation and direct electrolyte filling using a syringe.

Published Application Example

In Situ Raman Detection of Cuᵟ⁺–OH Species during CO₂-to-Ethylene Conversion: The cell used in this study, supplied by Beyond Battery under product code EC-RM4, an in situ Raman spectroelectrochemical cell, was used to monitor Cu/200-C₃N₄ during CO₂ electroreduction. Time-resolved spectra revealed signals assigned to Cu–CO₂, Cuδ⁺–OH, *OCCHO, *COO-related species, and adsorbed *CO. Combined with ATR-FTIR spectroscopy and DFT calculations, the results indicated that stabilized Cuδ⁺–OH species promoted asymmetric *CO–*CHO coupling, steering the reaction pathway toward ethylene.
