AbstractThe development of highly efficient and affordable electrocatalysts for the sluggish oxygen evolution reaction (OER) has been considered as a great challenge to the practical applications for water splitting and in rechargeable metal-air batteries. Herein, we report active and robust OER catalysts of Fe3+-doped beta-Ni(OH)(2) prepared via an atomic-scale topochemical transformation route. Based on the premise that all Fe3+ is incorporated into the beta-Ni(OH)(2) lattice, the OER activity increases directly with the content of Fe3+. The Fe(0.5)-doped beta-Ni(OH)(2) catalyst affords a current density of 10 mA cm(-2) at an overpotential as low as 0.26 V and a small Tafel slope of 32 mv dec(-1). Comparing the state-of-the-art IrO2 catalyst, the Fe(0.5)-doped beta-Ni(OH)(2) catalyst exhibits higher activity and stability from galvanostatic tests at 10 mA cm(-2). Additionally, we experimentally demonstrate that Fe(0.5)-doped beta-Ni(OH)(2) exerts higher OER activity than Fe(0.5)-doped alpha-Ni(OH)(2). All evidence indicates that Fe and the beta-Ni(OH)(2) matrix play an important role in NiFe-based catalysts.
