Electrochemical generation of ozone using a PEM electrolyzer at acidic pHs

Electrochemical Production of Hydrogen Peroxide in Perchloric Acid Supporting Electrolytes for the Synthesis of Chlorine Dioxide

“…However, because of the very fast interaction with hydrogen peroxide, they are not expected to be detected, and what we can see is simply their effect in the increased decomposition of hydrogen peroxide. 27 , 30 , 31 Additionally, it is important to take into consideration that oxygen solubility depends inversely on the salinity of the reaction media. Then, the higher the perchloric acid concentration is, the lower the concentration of dissolved oxygen is.…”

Exploring the pressurized heterogeneous electro-Fenton process and modelling the system

“…Apart from iron, that consumes it in the Fenton reaction (Eq. ( 1)), there can be other scavengers attacking hydrogen peroxide, such as radicals or other oxidants like ozone (which can be formed from oxygen oxidation at acidic conditions [48]). It is well known that ozone reacts with hydrogen peroxide to form radicals, which enhance the degradation of organic compounds.…”

A long-term-stable continuous flow electrochemical ozone generator with high current efficiency

“…7 Consequently, electrochemical ozone production (EOP) has raised increasing concern due to the advantages of low voltage operation, a small-scale and robust experimental set-up, and no gas feedstocks. [8][9][10] However, there are signicant challenges for PEM electrochemical ozonation generators, such as reducing low ozone concentrations and current efficiency due to competing oxygen evolution reactions in the electrolysis process. 11 Therefore, it is necessary to nd a suitable electrocatalyst to achieve high ozone selectivity, current efficiency and long-term operation stability.…”
