Electron enriched ternary NiMoB electrocatalyst for improved overall water splitting: Better performance as compared to the Pt/C || RuO2 at high current density

Iron-doped bimetallic boride Fe-Ni2B/NF-x nanoparticles toward efficient oxygen evolution reaction at a large current density

“…21 For example, Mo-doped NiB exhibited an overpotential value of 240 mV at a current density of 10 mA cm −2 in alkaline media. 22 Ternary Ni–Co–B via Co doping of NiB has also been reported and displays outstanding OER performance. 23 In particular, the incorporation of a small amount of Fe has an obvious optimization effect on OER activity compared to Mo or Co atoms.…”

In Situ Reactivating Perovskite Oxide Catalysts in Alkaline Water Electrolyzers: A Generalized Approach Based on Selective Cation Leaching

“…To obtain the ca. 0.5 V overpotential at the anode, we applied a constant potential bias of 2.2 V. The obtained current density was 150 mA cm –2 at which the estimated HER overpotential was 120 mV . The measured Ohmic loss of the cell was roughly 380 mV.…”
