In Situ Raman Spectroelectrochemical Cell (3H Gas Diffusion Type), Model: EC-RM3

Description

Product Overview

The EC-RM3 combines direct Raman access with a membrane-separated three-chamber configuration for gas-fed electrochemical studies. A dedicated gas channel supplies reactant gas to the working electrode in the cathode chamber, enabling operando investigation of gas–liquid–solid interfaces under three-electrode control.

Key Features

• Gas-Fed Interface Monitoring: Provides direct Raman access to the gas- diffusion cathode interface under continuous reactant gas supply.
• Membrane-Separated Reaction Control: Separates cathodic and anodic compartments to reduce product crossover and minimize inter-reaction interference.
• Operando Interfacial Analysis: Enables real-time investigation of reaction intermediates, catalyst evolution, and gas – liquid–solid interfacial processes.

Published Application Example

In Situ Raman Monitoring of CO₂ Electroreduction: The cell used in this study, supplied by Beyond Battery® under product code EC-RM3, a modified three-electrode flow-cell configuration, was used to investigate Cu₂O catalysts with controlled surface roughness during CO₂ electroreduction. Catalyst-loaded carbon paper served as the working electrode, with Ag/AgCl and a graphite rod as the reference and counter electrodes. In situ spectroscopy tracked *CO adsorption and Cu⁺ evolution, linking catalyst surface structure to C₂+ product selectivity.
