Ultrathin transition metal oxychalcogenide catalysts for oxygen evolution in acidic media

Nature Synthesis, Год журнала: 2025, Номер 4(3), С. 327 - 335

Опубликована: Янв. 2, 2025

Abstract Two-dimensional transition metal dichalcogenides (TMDs) exfoliated from bulk layered materials possess interesting properties. Most oxides are not and therefore cannot be exfoliated. Here we report the synthesis of a family ultrathin materials—transition oxychalcogenides (TMOCs)—and demonstrate their unique TMOCs (MX x O y , M = group IV or V metal, X chalcogen, oxygen; 0–2) 2 ) have been fabricated using tetrabutylammonium intercalation. The stoichiometry can adjusted, which enables control optical bandgaps tunability electrical conductivity by more than eight orders magnitude. By tuning chalcogen-to-oxygen ratio along with local atomic structure in TMOCs, it is possible to impart unexpected For example, contrast conventional TMDs, hybrid renders them surprisingly stable electrochemically active strong acids, allowing used as proof-of-concept catalysts for oxygen evolution reaction at pH ≈ 0. HfS 0.52 1.09 catalyst shows high mass activity (103,000 A g −1 an overpotential 0.5 V) exhibits durability proton exchange membrane water electrolysers.
