“…Aspects to be considered include electrode topographies and geometries, like the use of foams or other 3D electrodes to increase the active electrode surface area, or the insertion of turbulence promoters inside flow channels to increase mass transfer. [21] Improvement of electrochemical synthesis can also be achieved by reactor engineering, such as the use of parallel plate flow cells, [21] microchannel reactors, [27] or pulsing techniques combined with artificial intelligence. [28] Finally, to show applicability, the operation at scale with different loads at different current densities, as it can be expected from fluctuations from renewable electric power, needs to be addressed.…”

Five commercial materials were assessed for electrochemical conversion of n‐hexanoic acid by Kolbe electrolysis. Platinized titanium performed best, achieving a coulombic efficiency (CE) of 93.1±6.7 % (n=6) for the degradation of n‐hexanoic acid and 48.3±3.2 % (n=6) for the production of n‐decane, which is close to the performance of pure platinum (89.7±14.4 and 55.5±3.5 %; n=6). 56.7 mL liquid fuel was produced per mole n‐hexanoic acid, converting to an energy demand of 6.66 kWh and 1.22 € per L. Using optical profilometry and scanning electron microscopy coupled with energy‐dispersive X‐ray spectroscopy, it was shown that the degree of coverage of the titanium surface with platinum played the most important role. An uncovered surface of as little as 1–3 % already led to a deterioration of the CE of approximately 50 %. Using platinized titanium requires >36 times less capital expenditure at only <10 % increased operational expenditure; an electrode lifetime of 10000 h can be expected.

Applied electrochemistry (AE) plays today an important role in a wide range of fields, including energy conversion and storage, processes, environment, (bio)analytical chemistry, and many others. Electrochemical synthesis is now proven as a promising pathway to avoid all disadvantages in terms of high energy consumption and high pollution, while electrochemical modeling becomes a powerful tool to understand complex systems and predict and optimize the electrochemical devices under various conditions, which reduce study time and cost. The vital role of electrochemistry will greatly be considered in the upcoming years, aiming to reduce carbon footprints and supporting the transition towards a green and more sustainable energy framework. This review article summarizes the recent advances in applied electrochemistry. It shows how this field has become an indispensable tool for innovation, progress, problem-solving in the modern world, and addressing societal challenges across diverse fields.

“…87,88 The recent development of continuous flow electrochemical microreactors have been reviewed and discussed in detail in several reviews. [89][90][91] In addition to the benefits for continuous electrosynthesis, electrochemical device miniaturization can potentially improve the efficiency for electrochemistry HTE. Considering the relatively recent emergence of electrosynthesis, the examples of using miniaturized electrodes are still limited.…”

Electrochemical synthesis has recently emerged as an environmentally benign method for synthesizing value-added fine chemicals. Its unique reactivity has attracted significant interests of synthetic chemists to develop new redox chemistries. However, compared to conventional chemistry, the increased complexity caused by electrode materials, supporting electrolytes, and setup configurations create obstacles for efficient reaction discovery and optimization. The recent increasing adoption of high-throughput experimentation (HTE) in synthetic chemistry significantly expedites the synthesis development. Considering the potential of implementing HTE in electrosynthesis to tackle the challenges of increased parameter space, this short review aims at providing recent advances in the HTE technology for electrosynthesis, including electrocatalysts screening, device miniaturization, electroanalytical methods, artificial intelligence, and system integration. The discussed contents also cover some topics in HTE electrochemistry for areas other than synthetic chemistry, hoping to spark some inspirations for readers to use interdisciplinary techniques to solve challenges in synthetic electrochemistry.
