Abstract

In this paper, we report a facile method for the synthesis of MoS₂ nanosheet/ MoS₂ nanowire homostructures by growing MoS₂ nanosheets on the surface of MoS₂ nanowires. Benefiting from the uniform coating of MoS2 nanosheets on the surface of MoS2 nanowires, the MoS₂ nanosheet/ MoS₂ nanowire homostructures highly expose their electrocatalytic active edge sites and exhibit an enhanced electrocatalytic performance. It demonstrates a low overpotential of 107 mV at 10 mA/cm² and a small Tafel slope of 64 mV/dec in 0.5 M H₂SO₄. This work provides an inspiration for the design of efficient electrocatalysts with no stacking and aggregation structure.
