Photovoltaic-driven organic electrosynthesis and efforts toward more sustainable oxidation reactions

“…The field of organic photoelectrosynthesis has recently been profiled by Nguyen et al [95]. Since the enhancement of many electrochemical reactions by light can be readily achieved, the authors have given examples of RVC use in anodic oxidations to achieve cyclisation and functionalization.…”

The limitations of 2-dimensional electrodes can be overcome by using threedimensional materials having sufficient porosity and active area while offering moderate mass transport rates and a relatively low pressure drop at controlled electrolyte flow rate. In concept, a wide variety of metal, ceramic and composite materials are possible but restrictions are imposed by the need to avoid materials degradation, while maintaining adequate electrical conductivity, sufficient robustness and the possibility of facile scale-up. Despite its fragility, one of the traditional electrode materials used as a porous, 3-dimensional electrode is carbon foam, particularly in the 97% vol. porous form of reticulated vitreous carbon, RVC. A timeline indicates that the history of this material dates back over 50 years to the mid1960s, when it was primarily used as an uncoated material in small-scale, laboratory electroanalysis. Surface modification and diverse coatings have considerably extended the use of RVC. Recent applications are found in sensors and monitors, electrosynthesis, environmental processing and energy conversion. This review highlights the fundamental structure and summarises the physicochemical properties of RVC. Fluid flow through various porosity grades of the material, their active electrochemical area and rates of mass transport are quantified. The diverse applications of RVC in energy conversion, environmental treatment and electrosynthesis are illustrated by selected examples from the authors' laboratories and others over the last 30 years. Recent research on coated RVC, energy conversion environmental remediation and sensors is highlighted. Critical areas deserving further research and development are proposed.

“…Several features of the reactions deserve comment here. First, the conditions used for the synthesis of the furanose sugar were identical to the constant current electrolysis conditions developed for the simpler analogous tetrahydrofuran derivatives . The reaction setup can be exceptionally simple.…”

Constant current electrochemical reactions are very versatile tools for conducting oxidation and reduction reactions. In the reactions, the potential at the working electrode automatically adjusts to that of the substrate in solution, a situation that allows for the same overall synthetic approach to be used for both the direct oxidation and reduction of substrates and the generation of a wide range of chemical reagents and catalysts. The science presented in this manuscript illustrates how a combination of these methods can be used to create new opportunities for synthesis. Specifically, a direct constant current electrolysis was used to synthesize C‐glycoside derivatives that were then placed site‐selectively on a microelectrode array by using the same overall electrochemical approach to generate chemical reagents.
