MXene Anchored with Platinum Cobalt Alloy as an Efficient and Stable Electrocatalyst for Hydrogen Evolution.

ABSTRACT: It is a great challenge to prepare efficient and stable electrocatalysts for hydrogen evolution (HER) using non-precious metals. In this study, a series of PtCo/Ti₃C₂T_x-Y (Y: 16, 32, and 320, Y indicates the quality of Co(NO₃)₂) catalysts were synthesized by loading PtCo alloy on Ti₃C₂T_x. The PtCo/Ti₃C₂T_x-32 catalyst showed the best HER performance, reaching a current density of 10 mA cm^-2 with low overpotential (36 and 101 mV) and small Tafel slopes (66.37 and 105.17 mV dec^-1) in 0.5 mol L^-1 H₂SO₄ and 1 mol L^-1 KOH solution. The excellent HER activity of PtCo/Ti₃C₂T_x-32 ca
