Electrochemistry and Photoredox Processes

Electrochemistry since the days of Galvani, Volta and Faraday has always been, and still continues to be, an active cornerstone of Chemistry, the central science. Electrochemistry deals with the consequences of electron transfer processes and, therefore, contributes to fundamental chemical ideas and sustains the technological advances that underpin 21st century civilization. Electrochemical reactions are activated processes and require an energy input to proceed. Activation may be thermal, but it also can be photochemical.  Photoredox reactions, a subset of photochemical processes, involve light absorption, but depend on subsequent electron transfer steps which play a key role in the overall reaction mechanism. Hence, photo- and electrochemistry have been connected: photo-electrochemistry has always featured as a key aspect of electrochemical science and its associated technologies.

In the Section “Electrochemistry and Photoredox Processes”, this intimate connection is recognized, and important high-quality papers of general interest to the chemical community are welcome. This Section’s focus is, therefore, very broad and reflects the current worldwide interest in electrochemical and photoredox reactivity and systems. Consequently, contributions to this Section including full research articles, communications, reviews, and topical perspective papers in all areas of contemporary electrochemistry and photoredox processes and their technological applications are appropriate. Suggestions for Special Issues dealing with important current research themes of interest to the general readership are always welcome.
