Abstract

The article presents the design and synthesis of a heterostructure catalyst composed of yttrium ruthenate pyrochlore oxide (YRO) and defective NiFeP nanoparticles for enhancing the oxygen evolution reaction (OER). The study addresses the growing need for efficient and stable catalysts in advanced energy storage and conversion technologies. The authors explore the synergistic effects of defect engineering and transition metal-support interactions, which significantly improve the catalyst's performance. The YRO@D-NiFeP/Ru catalyst exhibits exceptional OER activity with a low overpotential and Tafel slope, as well as remarkable stability. The study provides insights into the development of state-of-the-art transition metal catalysts with multimetal oxide architecture, highlighting their potential applications in rechargeable metal-air batteries.
