a LSV curves for OER of LDH-Tixwt%/HCC (inset: overpotential at 10 mA cm-2). b Long-term durability test via chronopotentiometry conditions for 0.1 A cm-2 in a half-cell setup. c Faradaic efficiency of OER, along with the Idisk and Iring values, measured over a voltage range of 1.56 to 1.62 VRHE. d Current–Voltage (I–V) curves for AEMWE measured at 60 °C and 80 °C. e AEMWE durability test at 1 A cm-2. f XPS Ti 2p measured before and after 200 h of AEMWE operation. Half-cell test were conducted at room temperature (25 °C) in 1 M KOH (pH 14.0) using an RDE (32 μg cm-2, 2400 rpm). Durability test were conducted on a SUS mesh with a catalyst loading of ~1.6 mg cm-2. The measured potentials were not IR corrected (Rs = 4.3 ± 0.11 Ω).
