Synthesis of few-layered MoS 2 nanosheet-coated electrospun SnO 2 nanotube heterostructures for enhanced hydrogen evolution reaction
Abstract
In this work, we report the fabrication of low crystalline, few-layered MoS₂ nanosheet-coated electrospun SnO₂ nanotube (MoS₂/SnO₂) heterostructures with three-dimensional configurations by electrospinning combined with a one-step solvothermal approach. The morphologies and compositions of the as-prepared hybrid nanotubes were characterized by field-emission scanning electron microscopy, transmission electron microscopy, ICP-AES, BET method, X-ray diffraction and X-ray photoelectron spectroscopy. Results show that SnO₂ nanotubes are uniformly covered by sheet-like MoS₂ subunits on both outer and inner surfaces. The electrocatalytic activity of MoS₂/SnO₂ heterostructures towards a hydrogen evolution reaction was examined using linear sweep voltammetry and AC impedance measurements. It is shown that the MoS₂/SnO₂ modified electrode exhibits excellent catalytic activity for hydrogen evolution with low overpotential, a small Tafel slope and high current density.

Transition metal dichalcogenides (TMD) materials, such as MoS2, WS2, MoSe2, WSe2, and VSe2, are developed as potential alternatives to Pt-group electrocatalysts for HER due to their constrained electrons within two-dimensional layers.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
