Ambient Fast Synthesis and Active Sites Deciphering of Hierarchical Foam‐Like Trimetal–Organic Framework Nanostructures as a Platform for Highly Efficient Oxygen Evolution Electrocatalysis

Advanced Materials, Journal Year: 2019, Volume and Issue: 31(23)

Published: April 11, 2019

Metal-organic frameworks (MOFs) have attracted tremendous interest due to their promising applications including electrocatalysis originating from unique structural features. However, it remains a challenge directly use MOFs for oxygen because is quite difficult manipulate dimension, composition, and morphology of the with abundant active sites. Here, facile ambient temperature synthesis NiCoFe-based trimetallic MOF nanostructures foam-like architecture reported, which exhibit extraordinary evolution reaction (OER) activity as used catalyst in alkaline condition. Specifically, (Ni2 Co1 )0.925 Fe0.075 -MOF-NF delivers minimum overpotential 257 mV reach current density 10 mA cm-2 small Tafel slope 41.3 dec-1 exhibits high durability after long-term testing. More importantly, deciphering possible origination performed through characterization intermediates during OER process, where electrochemically transformed metal hydroxides oxyhydroxides are confirmed species.
