Bimetallic Intersection in PdFe@FeO<i>_x</i>‐C Nanomaterial for Enhanced Water Splitting Electrocatalysis

Abstract Supported Fe‐doped Pd‐nanoparticles (NPs) are prepared via soft transformation of a PdFe‐metal oraganic framework (MOF). The thus synthesized bimetallic PdFe‐NPs supported on FeO x @C layers, which essential for developing well‐defined and distributed small NPs, 2.3 nm with 35% metal loading. They used as bifunctional nanocatalysts the electrocatalytic water splitting process. display superior mass activity oxygen evolution reaction (OER) hydrogen (HER), both in alkaline acid media, compared those obtained benchmarking platinum HER catalyst, ruthenium, iridium oxide OER catalysts. also exhibit outstanding stability against sintering that can be explained by protecting role graphitic carbon layers provided organic linker MOF. Additionally, performance monometallic Pd/C NPs points to synergetic effect induced Fe–Pd interactions facilitates reaction. This is additional characterization prior post electrolysis TEM, XRD, X‐ray photoelectron spectroscopy, Raman revealing dispersed PdFe promote between Pd Fe, most likely Pd–O–Fe active centers.
