Hexagonal Sphericon Hematite with High Performance for Water Oxidation
Source abstract
Abstract
Abstract A cost‐effective hexagonal sphericon hematite with predominant (110) facets for the oxygen evolution reaction (OER) is demonstrated. Sequential incorporation of near‐atomic uniformly distributed Ce species and Ni nanoparticles into selected sites of the hematite induces a complex synergistic integration phenomenon that enhances the overall catalytic OER performance. This cheap hexagonal sphericon hematite (Fe ≈ 98%) only needs a small overpotential (η) of 0.34 V to reach 10 mA cm−2, superior to commercial IrO2 and more expensive Co‐, Ni‐, and Li‐based electrocatalysts.
