Electrochemical without using intentionally added supporting

Figure 9.4 Electrochemical flow microreactor system without using intentionally added supporting electrolyte. Electrochemical oxidation of furan.

Various electrochemical organic reactions have been carried out using electrochemical microflow reactors. Sometimes, electrolysis can be conducted without intentionally added supporting electrolyte by virtue of the extremely short distance between the anode and the cathode.

One of the most interesting features of electrochemical flow microreactor systems seems to be electrolysis without using an intentionally added supporting electrolyte by virtue of short distance between the electrodes. This field has attracted significant research interest, although various electrolyte-free electrochemical systems have been developed [17,18]. High electrode surface area to reactor volume ratios are also advantageous for conductivity and reaction efficiency.
