Vertically Aligned Interlayer Expanded MoS2 Nanosheets on a Carbon Support for Hydrogen Evolution Electrocatalysis
Abstract
<p>This work describes the facile microwave synthesis of interlayer expanded, nanosized MoS<sub>2</sub> sheets that are vertically aligned on a well-conducting reduced graphene (rGO) support, as confirmed by X-ray diffraction, Raman and X-ray photoelectron spectroscopy, scanning electron microscopy with energy dispersive X-ray analysis, and high-resolution transmission electron microscopy. Such structure has been predicted to be highly favorable for efficient electrocatalysis of hydrogen evolution by MoS<sub>2</sub> but could not be achieved until now. Films deposited from the microwave-synthesized MoS<sub>2</sub>-rGO composites demonstrate outstanding and stable hydrogen evolution performance in acidic solution. These catalysts exhibit an exchange current density as high as 1.0 ± 0.2 A g<sup>-1</sup> <sub>MoS2-rGO</sub>, sustain a current density of 10 mA cm<sup>-2</sup> (36 A g<sup>-1</sup> <sub>MoS2-rGO</sub>) at an overvoltage of 0.104 ± 0.002 V, and maintain steady performance for many hours. Importantly, our simple synthesis affords several advantages over more sophisticated methods used previously to prepare MoS<sub>2</sub> catalysts.</p>
