Efficient hydrogen evolution in transition metal dichalcogenides via a simple one-step hydrazine reaction
Abstract
<jats:title>Abstract</jats:title><jats:p>Hydrogen evolution reaction is catalysed efficiently with precious metals, such as platinum; however, transition metal dichalcogenides have recently emerged as a promising class of materials for electrocatalysis, but these materials still have low activity and durability when compared with precious metals. Here we report a simple one-step scalable approach, where MoO<jats:sub>x</jats:sub>/MoS<jats:sub>2</jats:sub> core-shell nanowires and molybdenum disulfide sheets are exposed to dilute aqueous hydrazine at room temperature, which results in marked improvement in electrocatalytic performance. The nanowires exhibit ∼100 mV improvement in overpotential following exposure to dilute hydrazine, while also showing a 10-fold increase in current density and a significant change in Tafel slope. <jats:italic>In situ</jats:italic> electrical, gate-dependent measurements and spectroscopic investigations reveal that hydrazine acts as an electron dopant in molybdenum disulfide, increasing its conductivity, while also reducing the MoO<jats:sub>x</jats:sub> core in the core-shell nanowires, which leads to improved electrocatalytic performance.</jats:p>
