Electrosynthesis is a fast-expanding field of research that is poised to play a critical role in the decarbonization of the chemical industry and the transition to green transformations for chemical production. This research area is less mature than traditional catalysis fields and innovations are typically scattered among multiple broad audience journals. Hence, this themed collection intends to bring this community together and share the latest original research, reviews, and perspectives on the electrosynthesis of chemicals and fuels.
This collection includes contributions on recent green advances in electrochemical transformations, including, but not limited to, hybrid processes that combine electrochemical with photo- or biocatalytic (microbial) transformations, catalyst development, electrolyzer cell designs, computational studies, and techno-economic analysis (with a focus on environmental concerns or life-cycle analysis).
