A facile chemical vapor deposition method to prepare single‐crystalline VS2 nanosheets for the hydrogen evolution reaction is reported. The electrocatalytic hydrogen evolution reaction (HER) activities of VS2 show an extremely low overpotential of −68 mV at 10 mA cm−2, small Tafel slopes of ≈34 mV d...
