Accelerated Hydrogen Evolution Kinetics on NiFe‐Layered Double Hydroxide Electrocatalysts by Tailoring Water Dissociation Active Sites

Advanced Materials, Journal Year: 2018, Volume and Issue: 30(10)

Published: Jan. 19, 2018

Abstract Owing to its earth abundance, low kinetic overpotential, and superior stability, NiFe‐layered double hydroxide (NiFe‐LDH) has emerged as a promising electrocatalyst for catalyzing water splitting, especially oxygen evolution reaction (OER), in alkaline solutions. Unfortunately, result of extremely sluggish dissociation kinetics (Volmer step), hydrogen (HER) activity the NiFe‐LDH is rather poor environment. Here novel strategy demonstrated substantially accelerating by partially substituting Fe atoms with Ru. In 1 m KOH solution, as‐synthesized Ru‐doped nanosheets (NiFeRu‐LDH) exhibit excellent HER performance an overpotential 29 mV at 10 mA cm −2 , which much lower than those noble metal Pt/C reported electrocatalysts. Both experimental theoretical results reveal that introduction Ru into can efficiently reduce energy barrier Volmer step, eventually kinetics. Benefitting from outstanding remained OER activity, NiFeRu‐LDH steadily drives electrolyzer current density cell voltage 1.52 V, values Pt/C–Ir/C couple state‐of‐the‐art overall water‐splitting
