摘要: 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 a one-step solvothermal approach. The morphologies and compositions as-prepared hybrid nanotubes were characterized field-emission scanning electron microscopy, transmission ICP-AES, BET method, X-ray diffraction photoelectron spectroscopy. Results show that are uniformly covered sheet-like subunits on both outer inner surfaces. electrocatalytic activity MoS2/SnO2 towards hydrogen evolution reaction was examined using linear sweep voltammetry AC impedance measurements. It is shown modified electrode exhibits excellent catalytic for overpotential, small Tafel slope high current density.
