Hierarchical Nanosheet‐Based MoS₂ Nanotubes Fabricated by an Anion‐Exchange Reaction of MoO₃–Amine Hybrid Nanowires

Moving onward and outward: MoO3–ethylenediamine (EDA) inorganic–organic hybrid nanowires were successfully transformed into hierarchical nanosheet-based MoS2 nanotubes (HNN-MoS2) by anion exchange with S2− anions at elevated temperature (see picture). The resulting nanotubes were highly active catalysts for photoelectrochemical hydrogen evolution by water splitting.
