From: Intrinsic metal-support interactions break the activity-stability dilemma in electrocatalysis
a Linear sweep voltammetry (LSV) curves of Ru/TiMnOx, Ru/MnOx, TiMnOx, and commercial RuO2 (Com. RuO2) in 0.5 M H2SO4 (pH = 0.3 ± 0.02), 0.5 M PBS (pH = 7.1 ± 0.10) and 1.0 M KOH (pH = 13.9 ± 0.03). Scan rate: 10 mV s-1. b Radar plot comparing the OER performance of Ru/TiMnOx and the reference samples in 0.5 M H2SO4 (pH = 0.3 ± 0.02). c–e Chronopotentiometry curves of Ru/TiMnOx for OER at 10 mA cm−2 in 0.5 M H2SO4 (c), 0.5 M PBS (d) and 1.0 M KOH (e), respectively. The potentials of chronopotentiometry tests are not iR-corrected.
