Effects of Sn content on Ti/RuO2–SnO2–TiO2 anodes used in the generation of electrolyzed oxidizing water
چکیده انگلیسی

As an excellent disinfectant, Electrolyzed Oxidizing Water (EOW) has less adverse effects on environment and the user. However, the cost of platinized Ti anode used in EOW generators restricts the application of EOW. Ti/RuO2–SnO2–TiO2 anodes were prepared by thermal decomposition method to replace platinized Ti anode in EOW generators. The properties of Ti/RuO2–SnO2–TiO2 electrodes were investigated by X-ray diffraction (XRD), Scanning Electron Microscope (SEM) and Differential scanning calorimetry (DSC). The electrochemical properties and accelerated life test were also studied. The EOW generated by Ti/RuO2–SnO2–TiO2 anodes had good quality. The results showed that: 450 °C was the optimal temperature for the preparation of anodes. In view of that an appropriate amount of Sn could efficiently refine grain size of coating and chlorine evolution potential of anode, the anodes with 7% Sn content had long accelerated life and low energy consumption for the generation of EOW. EOW had been used for eliminating Escherichia coli, of which sterilization effects significantly improved with increasing the ACC. Killing logarithm (KL) was 4.33 at an ACC of 12.4 mg/L and 5.76 at 33.1 mg/L.


► Pechini sol–gel method was used for the preparation of Ti/RuO2–SnO2–TiO2 anodes.
► The prepared anodes were used to replace the Platinized Ti anode used in EOW generators, which was less reported.
► It was appropriate to use the prepared anodes to replace the Platinized Ti anode.
► The optimal temperature for the preparation of anodes was 450 °C.
► The anodes with 7% Sn content had long accelerated life and low energy consumption for the generation of EOW.
