Self-standing 2D/2D Co₃O₄@FeOOH nanosheet arrays as promising catalysts for the oxygen evolution reaction

Abstract

Rational design of highly efficient oxygen evolution reaction (OER) is crucial for the practical application of water electrolysis. Herein, a hybrid Co3O4@FeOOH/NF electrode was fabricated by loading FeOOH sheets on...

The progress of research on vacancies in HMF electrooxidation

“…Surface defects, considered critical in electrocatalyst design, serve as key factors in modulating catalytic activity and selectivity ( Ares and Novoselov 2022 ; Yan et al, 2022 ). Among them, point defects, which encompass vacancies, substitutions, insertions, and interstitial atoms within the crystal lattice, can influence the electronic structure and surface reactivity of catalysts via doping or inherent mechanisms ( Xiang et al, 2019 ; Xiang and Wang 2022 ; Huang et al, 2023 ; Wang et al, 2023 ). Line defects, such as dislocations and grain boundaries, constitute one-dimensional imperfections altering the local electronic environment and surface morphology, potentially affecting catalytic activity.…”

Synthesis of porous LaNiO3 thin films by chemical solution deposition for enhanced oxygen evolution reaction

“…Recently, in order to obtain highly efficient OER electrocatalysts, various non-precious metal catalysts, such as transition metal-based oxides, perovskites, nitrides, and sulfides, have been developed. [11][12][13][14] Among these, perovskite oxides, which have a general formula of ABO 3 and include groups I-III metals for A and transition metals (Co, Fe, Ni, etc.) for B, have attracted great interest of researchers due to their low cost, high stability and tunable electronic structures.…”
