چکیده انگلیسی
Electrochemical ozone generation with ozone current efficiencies up to 33% and power consumption as low as 25 kWh kgâ1 O3 at room temperature using Ni/Sb-SnO2 anodes in a membrane electrode assembly (MEA) based cell with platinised titanium cathodes separated by Nafion membrane is reported. The complete decolourisation of 200 cm3 of 1000Â mg dmâ3 Reactive Blue 50 (RB50) dye within 8Â minutes at 2.7Â V with 100% current efficiency for the first 5Â minutes and specific power consumption as low as ca. 8 kWh kgCODâ1 using the MEA-based cell is also described. The byproducts of the dye oxidation were investigated and the formation of various organic acids confirmed.
