“…This can also generate a request for developing cheap (e.g. glucose) sensors that can be readily shared with underprivileged societies [4]. When extending our own perception by means of such a device, it is to be expected that electrochemistry will play an important role.…”

“…Based on the working principle of the SECCM, high‐speed imaging (approximately 3–4 orders of magnitude faster than conventional EC‐SPMs) was reported . Similar to SECCM is the earlier developed scanning droplet cell that is widely applied for locally resolved electrochemical reactivity studies, providing for instance information on single grains in a polycrystalline material and permitting the quick study of material libraries …”

surface coordination, strain effects, [6][7][8][9] ligand effects, [10,11] ensemble effects, [12] and the electrolyte composition. [13] A detailed understanding of these effects requires experimental and computational procedures to investigate the working mechanisms of the electrocatalysis. Ideally, atomically resolved topographic and chemical information of the catalyst surface under reaction conditions is required. Transmission electron microscopy (TEM) has been reported to be capable of in operando investigation of catalyst structures while catalytic reactions are taking place. [14] However, the instrumentation utilized for such purpose has very strong restrictions and realistic operating conditions cannot be easily applied so far. Alternatively, scanning probe microscopies (SPMs) and electrochemical scanning probe microscopies (EC-SPMs) are able to perform structural measurements of catalytic systems under reaction conditions with resolution down to atomic scales. Normally, EC-SPMs, for instance electrochemical scanning tunneling microscopy (EC-STM), electrochemical atomic force microscopy (EC-AFM), and scanning electrochemical potential microscopy (SECPM), can provide structural information on the solid side of the electrode/electrolyte interface at the atomic level for conductive samples (EC-STM is limited in the case of semi/nonconductive samples). However, these techniques usually lack the capability of chemical sensitivity, ultrahigh resolution reactivity monitoring, and probing the property of the electrolyte side of the interface. One well-developed exception is the scanning electrochemical microscopy (SECM), which will also be discussed in detail within this review. Additionally, SECM and related methods permit gleaning information about the electrolyte side of the electrochemical interface. However, the resolution of SECM and related methods is limited by the size of the SECM-probe and the working principle of SECM.In this review, first a very brief overview on electrocatalysis and on the importance of model substrates for understanding the fundamental underlying principles is given. Thereafter, the operational principle of different SPM techniques is summarized. The main focus of the work lies then on the application of the techniques to study phenomena important for electrocatalysis, including surface topography and adsorption processes. Within that context, also the application of room Improvements toward highly efficient electrochemical energy conversion require a detailed understanding of the underlying electrochemical processes at electrified solid-liquid interfaces. In situ and in operando studies by means of electrochemical scanning probe microscopy (EC-SPM) have become indispensable experimental tools due to their capability of resolving surface topography down to the atomic level even within the harsh environment of electrolytes. EC-SPM methodologies have thus contributed tremendously to the current understanding of electrocatalysis. In this review article, recent achievements in complement...
