Abstract:Inordertoaddress theisuesof lowenergyutilizationrateandhigh energyconsumptioninthechlor-alkali industry,a method using hydrosol to prepare ruthenium-titanium ( ⋅Ru-Ti) anode was proposed to enhance catalytic efficiency. TheRu-Tianodes underdiferentconditions were prepared byusing thehydrosol method.The efectsoftheconcentrationof hydrochloric acid precursor,the molar ratio of Ru -Tiand the number of coating layers on the chlorine evolution performance of the anodeswere studiedby X-raydifraction(XRD),linear sweep voltammetry(LSV),cyclic voltammetry(CV)and electrochemical impedance spectroscopy (EIS).The results show that the Ru -Ti anode prepared under the conditions of a precursor solution with a hydrochloric acid concentration of 1.5mol/L ,aRu-Ti molar ratio of 3:7 ,and 10 coating layers has the lowest chlorine evolution potential of 1.09V vs.SCE,which is much lower than the chlorine evolution potential of the graphite electrode 1.25V vs.SCE).The titanium-based Ru-Ti anode prepared by the aqueous sol-gel method under certain conditionshasexcelentelectrocatalyticchlorineevolutionperformance,oferingvaluableinsightsforthedevelopmentofhigh performance chlorine evolution anode materials.
