Waste Ti support from project-targeted industrial processes is RePaired by traditional Ta/Ir oxide formulation by brushing in August, 2023. Basic electrochemical fingerprits (FPs) are gained within newly-constructed (@G. Šekularac) OxyRePair-purposed electrolyzer setup:

Activity FP indicates the twinned Tafel slope for OER of 60 (low overpotentials) and 90 mV (high overpotentials). Operational activity at high currents of both RePaired anode and Electrolyzer obeys Ohm’s Low with anode resistance compensating fairly well the Ohmic drop contribution to apparent pure activity. This proves the full functionality and data reliability of newly-constructed electrolyzer for simultaneous measurements of anode (WE) electrochemistry and electrolysis performances for stability FP:

Cyclic voltammetry and capacitance complex plane plots indicate well-resolved anode behavior for morphology/activity/stability correlations. The stability FP@2 A/cm2 covers 3-V anode potential window below operational 6 V of operational potential and 9 V of electrolysis voltage to which cathode counterpart and electrolyte contribute with only 0.8  drop. The anode acceptably lasts for ca. 150 h/mgoxide at ca. 60 C electrolysis temperature. The setup is found highly efficient for the collection of reliable data relevant for OxyRePair realization. Operation FP was found suitable for pattern recognition analysis within cyclic exposed area:

Pattern recognition tool resolves quite well the area exposed both during activity/morphology (Left red rectangle) and stability FP (right red rectangle) tests.
