Two-Dimensional Tantalum Carbo-Selenide for Hydrogen Evolution.

ABSTRACT: Herein, we report the synthesis of two-dimensional Ta₂Se₂C (2D-Ta₂Se₂C) nanosheets using electrochemical lithiation in multilayer Ta₂Se₂C followed by sonication in deionized water. Multilayer Ta₂Se₂C was obtained via solid-state synthesis of Fe_xTa₂Se₂C followed by chemical etching of Fe. 2D-Ta₂Se₂C exhibited promising electrocatalytic activity for the hydrogen evolution reaction from water compared to multilayer Ta₂Se₂C and 2D-TaSe₂. 2D-Ta₂Se₂C showed an overpotential at 10 mA·cm^-2 (η₁₀) of 264 mV, a Tafel slope of 91 mV·dec^-1, and an electrochemically act
