Developing environmental friendly and low cost approach to improve electrocatalytic activity for hydrogen evolution reaction (HER) has drawn wide attention due to its significant value and challenge. NbS2 based materials exhibit high performance catalytic activity in electrochemical area, but its poor stability and synthetic difficulty limited the development and application. This work reported the enhancement of HER performance through utilization of conductive polymer polypyrrole (Ppy) on NbS2 nanowires as electrocatalysts, which can be easily prepared. The Ppy coated NbS2 nanowires obtain excellent catalytic activity for HER with low onset potential (-56 mV) and much lower overpotential (-219 mV) at current of -10 mA/cm2 compared with bare NbS2 nanowires.
