“…The electropromoted reactor has already been evaluated successfully for hydrocarbon oxidation and NO reduction by C 2 H 4 or C 3 H 6 in the presence of O 2 using both conventional thick films and thin sputtered noble metal electrodes. , Specifically, the MEPR with 22 Rh/YSZ/Pt parallel plate elements was found to promote selective catalytic reduction (SCR) of NO by 450% with near 100% selectivity to N 2 , even in high excess of O 2 (10%) at temperatures 200–300 °C (Figure ) . The corresponding Λ NO and Λ CO2 values were up to 2.4 and 350, respectively, and the rate enhancement ratio of complete C 2 H 4 oxidation was up to 900% .…”

“…A mildly oxidizing gas mixture was used at temperatures from 330 to 370 °C and flow rates between 1 and 30 L min –1 . It was found that positive potential applications can cause an increase of up to 200% in the catalytic oxidation rate of SO 2 with Faradaic efficiency values up to 30 at flow rates as high as 30 L min –1 , which corresponds to 3 × 10 4 h –1 space velocity or 0.1 s residence time . The MEPR can, conceptually, be scaled-up (or scaled-down) following a stack design and can, in principle, be used for many practical applications in exhaust treatment units and in chemical destruction or synthesis processes …”

“…The reactor is equipped of two external connecting wires for polarization purposes. This reactor has been used, for instance, for the oxidation of ethylene [33,34] and SO 2 [35] on Pt electrodes and reduction of CO 2 on Rh and Cu/TiO 2 electrodes [36]. Also, a MEPR with 22 Rh/YSZ/Pt plates was successfully tested under real conditions for the treatment of an automotive exhaust gas of a diesel engine [37,38].…”

“…Moreover, electro-oxidation of SO 2 possesses the advantages of high efficiency, compacted facility, and low operation costs . To undergo the process of the SO 2 oxidation reaction (SO 2 OR) on the anode, platinum and other novel catalysts have been served as a catalyst for the past decade. Of note, the photoelectrochemical method has been widely applied in pollutant removal from different conditions, possessing the advantages of a mild operation atmosphere and no pollution with sunlight as an energy source. In the photoelectrocatalytic process, the holes stimulated on the semiconductor surface have a strong ability to oxidize SO 3 2– to SO 4 2– , thereby overcoming the drawbacks of forced oxidation in the adsorption method.…”
