Rare earth-based alloy nanostructures show great potential as materials in the hydrogen evolution reaction (HER), and they have a relatively negative enthalpy of formation compared to traditional transition metal alloys, which resist dissolution alloys reaction. In addition, liner relationship can be observed d-band filling electrochemical activity. Therefore, rare nanostructure contains advantages transmission catalysts performs better selectivity stability. However, reduction potentials earth (RE) group are relevantly low, typically less than −1.9 V, synthesis methods RE very important. this Perspective, we generalize preparation method their applications related Through recent research on reaction, future development direction is pointed out.

Abstract The rational design of metal–organic framework (MOF)‐based electrocatalysts plays a key role in achieving high‐efficiency oxygen evolution reaction (OER). Herein, synergetic morphology and electronic structure engineering strategy are proposed to Co‐MOF nanoflower grown on carbon paper via rare‐earth cerium doping (CoCe‐MOF/CP). Compared with Co‐MOF/CP, the developed CoCe‐MOF/CP exhibited superior OER performance low overpotential 267 mV at 10 mA cm −2 outstanding long‐term stability over 100 h. Theoretical calculations show that unique 4f valence electron Ce induced charge redistribution surface through strong Co 3d‐O 2p‐Ce orbital coupling below Fermi level. Ce‐doped states sites endow them optimal free energy landscape for enhanced catalytic activity. This work provides new insights into comprehending RE‐enhanced mechanism electrocatalysis an effective MOF‐based electrocatalysts.

Developing low-cost electrocatalysts with excellent activity and durability in urea-assisted water splitting is urgently needed order to achieve sustainable hydrogen production. Herein, we situ synthesized a robust coupled heterostructured electrocatalyst (CoP/MoO2) on nickel foam (NF) substrate explored its electrocatalytic performances the evolution reaction (HER), oxygen (OER), urea oxidation (UOR). The overpotential of CoP/MoO2/NF found be only 11 mV at 10 mA cm–2 during HER process, which significantly lower than that commercial Pt/C. Meanwhile, UOR catalytic performance indicates fast kinetics, along considerable low driving potential (1.26 V) compared OER (1.51 V). In ex techniques demonstrate these properties are mainly ascribed effective synergistic effect strong electronic interactions between single-component CoP MoO2, can tune states Co Mo, expose more active sites, enhance intrinsic activity, accelerate charge transfer. Moreover, when used electrochemical overall electrolysis, reach current density 1.46 1.32 V. This outperforms Pt/C||RuO2 numerous nonprecious metal maintains stable long-term electrolytic operation for 84 h. work provides promising pathway development efficient catalysts electrolysis
