title: Comparative study on the catalytic electrooxidative abilities of RuO(x)-PdO-TiO(2)/Ti and RuO(x)-PdO/Ti anode.
abstract: Comparative study of the catalytic electrooxidative abilities of RuO(x)-PdO/Ti and RuO(x)-PdO-TiO(2)/Ti were conducted using Active Orange 5R solution as simulated wastewater. RuO(x)-PdO-TiO(2)/Ti anode possesses higher catalytic oxidation ability, as compared to RuO(x)-PdO/Ti, in both direct oxidation and indirect oxidation processes. RuO(x)-PdO-TiO(2)/Ti could provide a discoloration rate of 98.14% within 30 min, while the COD removal could reach 51.43% in 120 min. It was indicated that higher electrooxidation ability could be achieved at RuO(x)-PdO-TiO(2)/Ti anode, which exhibited lower chlorine evolution potential and higher oxygen evolution potential probably resulted from the higher oxidation states of Ru and Pd.
