Direct Electroplating Ruthenium Precursor on the Surface Oxidized Nickel Foam for Efficient and Stable Bifunctional Alkaline Water Electrolysis

Advanced Materials, Год журнала: 2024, Номер 36(31)

Опубликована: Июнь 6, 2024

Abstract Water electrolysis to produce hydrogen (H 2 ) using renewable energy is one of the most promising candidates for realizing carbon neutrality, but its reaction kinetics hindered by sluggish anodic oxygen evolution (OER). Ruthenium (Ru) in high‐valence state (oxide) provides active OER sites and less costly, thermodynamically unstable. The strong interaction between Ru nanoparticles (NPs) nickel hydroxide (Ni(OH) leveraged directly form Ru–Ni(OH) on surface a porous foam (NF) electrode via spontaneous galvanic replacement reaction. formation Ru─O─Ni bonds at interface NPs Ni(OH) (Ru–Ni(OH) oxidized NF significantly enhance stability /NF electrode. In addition OER, catalyst enough (HER). As result, it able deliver overpotentials 228 15 mV reach 10 mA cm −2 HER, respectively. An industry‐scale evaluation as both HER electrodes demonstrates high current density 1500 (OER: 410 mV; HER: 240 mV), surpassing commercial RuO 600 mV) Pt/C based performance (HER: 265 mV).
