Cobalt Sulfide Nanosheet/Graphene/Carbon Nanotube Nanocomposites as Flexible Electrodes for Hydrogen Evolution
説明
<jats:title>Abstract</jats:title><jats:p>Flexible three‐dimensional (3D) nanoarchitectures have received tremendous interest recently because of their potential applications in wearable electronics, roll‐up displays, and other devices. The design and fabrication of a flexible and robust electrode based on cobalt sulfide/reduced graphene oxide/carbon nanotube (CoS<jats:sub>2</jats:sub>/RGO‐CNT) nanocomposites are reported. An efficient hydrothermal process combined with vacuum filtration was used to synthesize such composite architecture, which was then embedded in a porous CNT network. This conductive and robust film is evaluated as electrocatalyst for the hydrogen evolution reaction. The synergistic effect of CoS<jats:sub>2</jats:sub>, graphene, and CNTs leads to unique CoS<jats:sub>2</jats:sub>/RGO‐CNT nanoarchitectures, the HER activity of which is among the highest for non‐noble metal electrocatalysts, showing 10 mA cm<jats:sup>−2</jats:sup> current density at about 142 mV overpotentials and a high electrochemical stability.</jats:p>
