About this collection
We are delighted to share with you a selection of the papers associated with a Faraday Discussion on Electrosynthesis. More information about the related event may be found here: http://rsc.li/electrosynthesis-fd2023. Additional articles will be added to the collection as they are published. The final versions of all the articles presented and a record of the discussions will be published after the event.
Organic electrosynthesis initially emerged in the field of synthetic chemistry as an intrinsically green method to replace hazardous chemicals by electrons for oxidations and reductions. In recent years it has been shown to offer unique opportunities to increase conversion efficiencies and synthesize new molecules that are not accessible thermochemically or photochemically and not accessible from petroleum. It can also be used to streamline biocatalysis and chemocatalysis in biorefineries, manufacture chemicals from regional- and community-scale quantities of agricultural waste, and in the pharmaceutical and chemical industries to access fine chemicals in a more efficient and sustainable fashion. Nevertheless, many of these efforts remain exploratory as a fundamental understanding of the elementary processes involved in these transformations is still lacking. This meeting will bring together synthetic chemists, physical chemists, material scientists, electrochemists, computational scientists, and engineers to harness the transformative knowledge required to develop this technology. This meeting will cover 3 main themes: Organic electrosynthesis, Electrofuels and ElectrofuelsFlow cells and reactor design.
On behalf of the Scientific Committee, we hope you join us and participate in this exciting event, and that you enjoy these articles and the record of the discussion.
