Abstract
Hydrogen peroxide can be produced electrochemically by selective oxygen reduction reaction or selective water oxidation reaction in various electrolytes. A very promising, sustainable, and efficient method to produce hydrogen peroxide is the so-called electrochemical “lab-on-a-chip” technology, where microfluidic electrochemical flow cells can be used. The main advantage of such a system is “on demand” and “on site” production. If these systems are to be commercialized, suitable electrocatalysts (anode and cathode), sensors, and a device design must be developed and interconnected. Such technology could then eventually be deployed in an industrial environment with internal/external numbering-up approach.
