Scanning electrochemical microscopy (SECM) is coupled with surface-enhanced Raman scattering (SERS) microscopy to characterize local surface modifications. SECM is utilized for the surface patterning of para-nitrothiophenol self-assembled monolayers

In pursuance of efficient tools for the local analysis and characterization of novel photoelectrocatalytic materials, several SECM-based techniques have been developed, aiming on the combined benefit of a local irradiation of the analyzed sample and

The onset potential of an electrocatalytic reaction is frequently used as an indicator to compare the catalytic performance of electrocatalysts. However, in addition to the fact that the onset potential is an undefined physico-chemical value which is

Feedback-mode scanning electrochemical microscopy (SECM) was conducted with in situ control of the sample temperature using a Peltier element. The intrinsic heat pulsing of the temperature control feedback loop causes the sample position to oscillate

A method to determine localized temperature profiles using a scanning electrochemical microscopy (SECM) setup and potentiometry is presented. A Pt microelectrode was first calibrated to correlate the open circuit potential (OCP) with temperature in a

Ring-disk microelectrodes are proposed to be applied in a double constant-current mode using simultaneously an irreversible and a reversible reaction at the SECM tip. This allows an independent determination of the tip-to-sample distance concomitantl
