A compact cell designed to enable real-time investigation of chemical and structural transformations occurring at electrode-electrolyte interfaces during electrochemical operation. By combining electrochemical control with Raman spectroscopy, the system allows you to directly observe surface reactions as they occur under applied potential, providing molecular-level insight into dynamic electrochemical processes. Using a top-illumination configuration, the laser beam is directed through a quartz optical window onto the working electrode surface while electrochemical measurements are performed simultaneously. This enables monitor dynamic events as they occur, including transient reaction intermediates, molecular adsorption, catalyst restructuring, phase transformations, and surface chemical evolution during operation.
The in-situ Raman electrochemical cell typically adopts a three-electrode configuration with gas inlet/outlet. This cell comes with three electrodes: a platinum coil counter electrode, an Ag/AgCl reference electrode, and a platinum working electrode holder allowing rapid installation of a user-defined substrate or catalyst platform and positioning close to the optical window for efficient signal collection. The cell accommodates a wide range of working electrode formats including conductive carbon paper, catalyst-coated glassy carbon, metal foils, conductive glass, metal meshes, and porous electrodes. This flexibility supports both conventional electrochemical Raman measurements and enhanced methodologies including SERS and SHINERS-based studies.
Note: Detachable L-shaped Glassy Carbon Electrodes can be used with the Cell to reduce the distance between the WE and the Window.
Raman electrochemical cells find versatile applications across electrocatalysis, energy storage, and interfacial electrochemistry research. They are widely used to investigate reaction mechanisms for hydrogen evolution and oxidation (HER/HOR), oxygen evolution and reduction (OER/ORR), carbon dioxide and nitrogen reduction (CO2RR/NRR), and fuel cell processes through real-time observation of catalyst evolution and reaction intermediates. In battery research, they enable studies of Li-ion and Na-ion intercalation/deintercalation, electrode phase transitions, and solid electrolyte interphase (SEI) formation. Additional applications include metal-air battery systems such as Zn-air chemistries, photoelectrochemical devices, corrosion and surface science studies, and investigations of molecular adsorption and surface interactions in sensing and functional materials.
