The past two decades have seen a renewed and rapidly growing interest in the fields of electrochemistry and electrocatalysis. This is on the one hand stimulated by applications in energy conversion and energy storage, where highly efficient electrochemical or electrocatalytic processes are considered to be an indispensable part of modern energy concepts based on the use of renewable energy sources. However, it is also pushed by the rapid development of modern in situ spectroscopy and microscopy tools as well as the enormous progress that has been made in the theoretical description of processes occurring at the electrochemical solid–liquid interface. This Thematic Series provides a broad perspective covering a variety of important topics in modern electrocatalysis research, with a clear focus on the nanoscale understanding of the relevant processes.
