Abstract:	摘要： AbstractFlexible 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 (CoS2/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 CoS2, graphene, and CNTs leads to unique CoS2/RGO‐CNT nanoarchitectures, the HER activity of which is among the highest for non‐noble metal electrocatalysts, showing 10 mA cm−2 current density at about 142 mV overpotentials and a high electrochemical stability. 其他題名： Angew.
