Metal oxide electrocatalyst support for carbon-free durable electrodes with excellent corrosion resistance at high potential conditions

Abstract

Ti₂O₃ was used as a corrosion-resistive catalyst support for electrocatalytic reactions at high potential conditions. The model electrocatalyst/Ti₂O₃ electrode, BSCF/Ti₂O₃, demonstrated a considerably higher durability than a carbon support at a highly oxidative potential and completely retained its OER performance after 2000 repeated potential cycles. Therefore, Ti₂O₃ is promising as a conductive support for electrochemical catalytic reactions at high potential conditions.
