Hydrogen peroxide generated from the electrochemical reaction with oxygen is particularly interesting due to its growing demand. Although most research has focused on highly active and stable electrocatalysts for H2O2 generation, substantial challenges still impede the industry–relevant scale application of producing liquid H2O2 solution via electrochemical methods. This review emphasizes the difficulties of making highly concentrated H2O2 products without other electrolyte impurities regarding the catalyst–electrolyte interface and reactor engineering. Furthermore, we discuss the possibility of direct in-situ consumption of H2O2 to other thermo-/electrochemical oxidation reactions even at low concentrations, even with salt ions. This approach allows the electrochemical route to become more competitive in the future.
