INNOVATIVE METHOD FOR THE SYNTHESIS OF Ti/SnO2-Sb ANODES USING POLYVINYL ALCOHOL

In electrochemical oxidation, non-active anodes are particularly promisingdue to their ability to facilitate the oxygen release reaction at high potentials. In thisstudy, we synthesized non-active Ti/SnO2-Sb (94:6) anodes using polyvinyl alcohol asa solvent for the metal precursors, aiming to increase stability and improveelectrocatalytic properties. The anodes were prepared via thermal deposition, and theeffects of three different calcination temperatures (500, 550, and 600 °C) weresystematically investigated, with a heating rate of 3 °C min⁻¹. Physical andelectrochemical characterizations revealed that the anode synthesized at 600 °Cpresented a more uniform coating, resulting in an operational lifetime of 5.9 hours.Thus, the calcination temperature impacts the performance of Ti/SnO2-Sb anodes.
