Single atoms are superior electrocatalysts having high atomic utilization and amazing activity for water oxidation and splitting. Herein, this work reports a thermal reduction method to introduce high‐valence iridium (Ir) single atoms into bimetal phosphide (FeNiP) nanoparticles toward high‐efficiency oxygen evolution reaction (OER) and overall water splitting. The presence of high‐valence single...
Heterostructures have attracted increasing attention due to their amazing synergetic effects, which may improve the electrochemical properties, such as good electrical/ionic conductivity, electrochemical activity, and mechanical stability. Herein, novel hierarchical Fe2O3@Ni3Se4 nanotubes are successfully fabricated by a multistep strategy. The nanotubes show length sizes of ≈250–500 nm, diameter...
Pt‐IrO2 nanorod arrays supported on the carbon paper were fabricated directly using the dip‐coating/calcination method. The nanorod arrays and ordering were characterized by scanning electron microscope. Pt‐IrO2/carbon paper directly used as catalyst layer and support layer with the united structure on the anode side is demonstrated to have excellent electrocatalytic activity for oxygen evolution...
