Development of spectroelectrochemical microscopy for the real-time study of electrochemical surface processes.

ABSTRACT: We present a multimodal methodology integrating time-resolved inductively coupled plasma mass spectrometry (ICP-MS) with operando reflected microscopy to characterise electrochemical surface processes. Enabled by a custom scanning flow cell, this approach allows simultaneous high-resolution optical inspection under controlled polarisation and continuous electrolyte flow. While ICP-MS and reflected microscopy have each advanced the study of electrocatalysis and corrosion, their direct combination correlates spatially resolved optical changes with quantitative, time-dependent dissolution kinetics. To illustrate its potential, we examined copper electrodes in dilute NaCl solutions with and without 2-mercaptobenzothiazole (2-MBT), a well-established corrosion inhibitor. The joint analysis dist
