As a classic transition metal dichalcogenide, WS2 has been synthesized by a variety of methods towards different applications. However, few of them are vertically grown self-templated structures, besides, all the reported WS2 for hydrogen evolution reaction (HER) are in acidic media. Herein, we use a simple method to synthesize a new morphological WS2 triangular nanoplates array through the sulfuration of hydrothermally obtained WO3 nanowires on carbon cloth (WS2TN/CC). The WS(2)TNs are equilateral triangle with large surface area that grown vertically on carbon fiber. The WS2TN/CC exhibits good catalytic activity and stability as electrocatalyst for HER in acidic media and firstly in both neutral and alkaline media. The overpotential of 196, 150 and 193 mV are needed to afford current density of 10 mA cm (2) in acidic, neutral and alkaline media, respectively. (C) 2019 Hydrogen Energy Publications LLC.
