CNB-12-EC-RM3
In-situ Raman Spectroelectrochemical Cell Model:EC-RM3
EC-RM3 In Situ Raman Spectroelectrochemical Cell
A three-chamber gas-diffusion spectroelectrochemical cell for operando Raman monitoring of gas-fed electrochemical interfaces.
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 delivers 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 a continuous supply of reactant gas.
Membrane-Separated Reaction Control
Separates the cathodic and anodic compartments to reduce product crossover and minimize interference between electrode reactions.
Operando Interfacial Analysis
Enables real-time investigation of reaction intermediates, catalyst evolution, and gas–liquid–solid interfacial processes.

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