Electrochemical Reactions in Microreactors

Applications of Flow Microreactors in Electrosynthetic Processes

“…This feature is regarded as the prime advantage of a flow microreactor and allows these devices to provide ideal environments for heterogeneous processes, such as electrochemical reactions based on electron transfer between electronic and ionic conductors. For this reason, various electrochemical systems using flow microreactors have been developed for use in electrosynthesis, − electrochemical analysis and sensing, − fuel cell technology, − and other applications. Thus, the most distinctive feature of such microreactors developed is an interelectrode gap or flow channel width and depth in the range of a few micrometers up to 1 mm.…”

Advances in electro- and sono-microreactors for chemical synthesis

“…Electrodes stacked in a parallel plate-to-plate fashion in which two electrode plates are separated by isolating spacers to produce a parallel flow channel has become a popular choice of micro-technology. 3,13,14 This type of flow cell has now been reported for use in many laboratory electrosyntheses 15–23 and commercial usage. 13,24–26 All parallel plate cells can be run as divided or undivided cells.…”

Translating batch electrochemistry to single-pass continuous flow conditions: an organic chemist’s guide

“…In addition to reduced waste generation, the atom economy of electrochemical methods is most often superior to conventional procedures. The resurgence of organic electrochemistry has been accompanied by an increased attention to flow electrochemistry [6][7][8][9][10]. Implementation of flow cells is widely recognized as the appropriate method for the scale-up of electrochemistry.…”

“…Flow cells typically consist of two flat electrodes placed in parallel with a narrow distance (< 1 mm) between them [6][7][8][9][10]. The solution of reactants solution is then flown through the gap, where the electrolysis occurs.…”
