Abstract

Free-standing and flexible WS<sub>2</sub> /WO<sub>2.9</sub> /C hybrid membranes are synthesized and used as catalytic electrodes for electrochemical hydrogen evolution, exhibiting a high and stable catalytic activity. By virtue of the synergetic effect, a low onset overpotential of 20 mV and a Tafel slope of 36 mV dec<sup>-1</sup> are achieved.
