原位制备铁钴镍层状氢氧化物作为高效稳定的析氧反应催化剂
In situ fabrication of FeCoNi Layered Hydroxides as efficient and stable catalyst for oxygen evolution reaction
摘要
Abstract
The development of efficient and durable oxygen evolution electrocatalysts to improve electrochemical performance is of great significance for energy conversion systems.Report a direct room temperature stirring strategy,in situ preparation of FeCoNi layered hydroxide nanomaterials(FeCoNi-LDHs)using homemade CoNi-glycerate solid spheres as precursor.FeCoNi-LDHs exhibits a layered core-shell structure,numerous ultra-thin layered hydroxide nanosheets forming the walls.Due to the unique structure and composition adjustment of FeCoNi-LDH-5 only needs an overpotential of 182 mV for the OER to drive a current density of 10 mA·cm-2,and shows good electrochemical stability.The significant increase in activity can be attributed to the realization of a larger electrochemically active surface area and a lower transfer resistance.The study provides a new approach for designing LDHs as efficient and promising OER electrocatalysts.关键词
