Product Overview
The Operando Electrochemical Scanning Tunneling Microscope (EC-STM) combines scanning tunneling microscopy with electrochemical measurements, enabling real-time atomic- or nanoscale imaging of electrode surfaces under actual electrochemical operating conditions. While the electrode is immersed in an electrolyte and undergoing electrochemical reactions, the system can simultaneously monitor surface morphology and structural changes together with electrochemical signals such as potential and current. This provides direct spatially resolved insight into the dynamic structure and evolution of electrode–electrolyte interfaces, making it a powerful tool for investigating reaction mechanisms, surface reconstruction, active sites, and structural changes in electrocatalysis, energy materials, batteries, corrosion, and surface science.
Product Advantages
Atomic-scale spatial resolution: Provides localized surface structural information that conventional electrochemical techniques cannot resolve, down to individual surface features and atomic-scale structures.
Synchronized microscopy and electrochemistry: Enables electrochemical signals such as current and potential to be correlated directly with microscopic observations for structure–performance analysis.
Strong capability for dynamic studies: Captures processes such as surface reconstruction, deposition, dissolution, and adsorption instead of relying only on before-and-after characterization.
Measurements under liquid conditions: Allows experiments to be performed directly in electrolyte environments, providing conditions closer to practical electrochemical operation.
Localized surface analysis: Makes it possible to distinguish different regions of an electrode surface and investigate local activity and heterogeneity.
Direct structure–activity correlation: Helps connect changes in surface structure with electrochemical performance, providing valuable evidence for reaction-mechanism studies and material optimization.
Main Product Features
Dedicated electrochemical STM cell: Designed for measurements at electrode–electrolyte interfaces under controlled electrochemical conditions.
Integrated STM and electrochemical operation: Combines microscopic imaging with standard electrochemical measurement workflows and modes.
Highly sensitive tunneling-current detection: Obtains surface information by detecting extremely small tunneling currents between the probe and sample.
Coordinated experimental control: Allows STM scanning parameters and electrochemical conditions such as electrode potential to be controlled within the same experimental workflow.
Compatibility with various electrode materials: Suitable for conductive surfaces including metals, single crystals, thin films, and other electrode materials.
Repeated scanning and area tracking: Enables sequential measurements of the same surface region to follow changes during an experiment.
Multi-scale characterization: Combines localized surface information from STM with macroscopic electrochemical responses for a more comprehensive analysis of electrode behavior.
Application Areas
Electrocatalysis: Investigation of electrode surface evolution and reaction mechanisms in HER, OER, CO₂ reduction, ORR, and other electrochemical reactions.
Fuel Cells & Water Electrolysis: Study of catalyst surface restructuring and degradation under operating conditions.
Batteries & Energy Storage: Characterization of surface reconstruction, deposition, dissolution, and interfacial changes during charge–discharge processes.
Corrosion Science: Investigation of localized surface changes and corrosion mechanisms under electrochemical conditions.
Electrodeposition & Surface Engineering: Study of nucleation, growth, deposition, and surface modification processes at the electrode interface.
Electrode–Electrolyte Interface Research: Investigation of adsorption, desorption, surface restructuring, and other interfacial processes at the microscopic level.
Fundamental Surface Science: Characterization of conductive surfaces such as single crystals, metals, and thin films under different electrochemical conditions.
