Abstract Developing highly active and stable electrocatalysts for hydrogen production at industrial current densities is pivotal to give an impetus carbon neutrality. Recently, metal–organic frameworks (MOFs) with large surface area adjustable structures have become a class of promising alternative electrocatalysts, while their low conductivity poor stability limit widespread applications. Here, modified strategy proposed stabilize modulate Ruthenium (Ru) species including Ru single atoms (Ru SAs) nanoparticles NPs) on MOFs enhanced evolution reaction (HER). Benefiting from the strong interaction between MOFs, synthesized NiFeRu SA+NP ‐DOBDC (DOBDC: 2,5‐dioxido‐1,4‐benzenedicarboxylate) exhibits extraordinary HER performance overpotentials 25 271 mV 10 1000 mA cm −2 , respectively. Meanwhile, it enables robust high density 1 A over 300 h. Remarkably, assembled anion exchange membrane (AEM) electrolyzer realizes voltage alkaline water electrolysis. In situ analyses demonstrate that optimized H 2 O adsorption dissociation, theoretical calculations indicate SAs NPs accelerate Volmer‐Heyrovsky pathway, synergistically promoted performance. This work presents competitive integrate supported metal platform efficiently drive

Inorganic–organic hybrid cobalt spinel oxides for catalyzing the oxygen evolution reaction

Nature Communications, Год журнала: 2025, Номер 16(1)

Опубликована: Март 12, 2025

Fully triggering the deep-seated potential of traditional nanomaterials, such as classic spinel family, is paramount importance in field materials science, which yet believed to heavily depend on advanced conceptual designs and synthetic strategies. Herein, a type inorganic–organic hybrid oxide designed using π-conjugated azobenzene single-tooth coordination method overcome their stubborn problems moderate activity phase instability electrocatalytic reactions. Taking Co3O4 nanocubes pre-catalyst, after subtle etching cube surfaces, some oxygen atoms tetrahedral Co–O are replaced selectively linked weakly polar azo-extended units (π*–N=N–π*) via electrophilic carboxyl groups. The π-conjugation structure suppresses covalency competition between octahedral fields, successfully preventing transition during process improving durability. This study not only expands family but also provides useful guidelines for developing functional materials. Unlocking nanomaterials like oxides crucial catalytic evolution reaction. Here, authors report an that enhances both structural stability through method.
