Metal-support interaction boosted electrocatalysis of ultrasmall iridium nanoparticles supported on nitrogen doped graphene for highly efficient water electrolysis in acidic and alkaline media
Abstract
Abstract Strong metal-support interaction has been explored as an efficient way in heterogeneous catalysis to modulate the electronic structure of active metal for enhanced catalytic activity. Herein we report ultrasmall iridium nanoparticles supported on nitrogen-doped graphene sheets (Ir@N-G-750) with boosted electrocatalytic activity and durability toward hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) for highly efficient water electrolysis. As-reported Ir@N-G-750 demonstrates excellent HER and OER activity superior to benchmarking Pt/C and RuO2/IrO2 catalysts, respectively in both acidic and alkaline media; as a bifunctional electrocatalyst, it enables long-term 1.6 V-overall water splitting at 20 mA cm−2 current density when loaded on planar glassy carbon electrode at a total Ir loading of 23 μg cm−2. Detailed investigation unveils abundant Ir–N coordination in Ir@N-G-750, which enhances the electron density and modifies electronic structure of Ir nanoparticles to facilitate the electrochemical reactions. Density functional theory (DFT) calculation indicates that N dopants can stabilize the supported Ir clusters and improve their electrocatalytic activities.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
