Abstract
The hydrogen evolution reaction (HER) via water splitting requires the development of advanced and inexpensive electrocatalysts to replace expensive platinum (Pt)-based catalysts. The scalable hydrothermal synthesis of SnS on N-reduced graphene (N-rGr) sheets is presented for the first time, which is used as a highly-active electrocatalyst with long-term stability in acidic, neutral, and alkaline media. This hybrid catalyst reveals a low overpotential of −125 mV, Tafel slope of 38 mV dec−1, exchange current density of 6.23 mA cm−2, onset potential of 59 mV, and long-term durability.
