Electro-oxidation flue gas desulfurization is a gas–liquid reaction, but the solubility of SO 2 in aqueous solution is very low with the solubility of only 9.4 g/100 mL at 25 °C. Thus it is necessary to strengthen the contact between SO 2 and ROSs to achieve successful flue gas desulfurization. Namely, the mass transfer of flue gas in electrolyte should be strengthened [314,315].
