Improving the Oxygen Evolution Activity of Layered Double‐Hydroxide via Erbium‐Induced Electronic Engineering

Small, Journal Year: 2022, Volume and Issue: 19(5)

Published: Nov. 29, 2022

Layered double-hydroxide (LDH) has been considered an important class of electrocatalysts for the oxygen evolution reaction (OER), but adsorption-desorption behaviors intermediates on its surface still remain unsatisfactory. Apart from transition-metal doping to solve this electrocatalytic problem LDH, rare-earth (RE) species have sprung up as emerging dopants owing their unique 4f valence-electronic configurations. Herein, Er is chosen a RE model improve OER activity LDH via constructing nickel foam supported Er-doped NiFe-LDH catalyst (Er-NiFe-LDH@NF). The optimal Er-NiFe-LDH@NF exhibits low overpotential (191 mV at 10 mA cm-2 ), high turnover frequency (0.588 s-1 and activation energy (36.03 kJ mol-1 which are superior Er-free sample. Electrochemical in situ Raman spectra reveal facilitated transition Ni-OH into Ni-OOH promoted kinetics through effect. Theoretical calculations demonstrate that introduction facilitates spin crossover valence electrons by optimizing d band center NiFe-LDH, leads GO -GHO closer kinetic volcano balancing bonding strength *O *OH. Moreover, presents practicability electrochemical water-splitting devices with driving potential well-extended period.

Iron Oxyhydroxide: Structure and Applications in Electrocatalytic Oxygen Evolution Reaction

Advanced Functional Materials, Journal Year: 2023, Volume and Issue: 33(25)

Published: March 10, 2023

Abstract Oxygen evolution reaction (OER) is the anodic half‐reaction for crucial energy devices, such as water electrolysis, metal–air battery, and electrochemical CO 2 reduction. Fe‐based materials are recognized one of most promising electrocatalysts OER because its extremely low price high activity. In particular, iron oxyhydroxide (FeOOH) not only highly active toward OER, but also widely accepted true species plenty converted into FeOOH during test. Herein, recent advances FeOOH‐based nano‐structure application in reviewed. The relationship between structure catalytic performance, followed by introduction current strategies enhancing activity (i.e., crystalline phase engineering, element doping, construction hybrid materials) mainly focused. Finally, a summary perspective about remaining challenges future opportunities this area further design provided.
