This article reports, for the first time, the application of Nb4C3Tx in the MXene series satisfying the formula of Nb4C3Tx in the field of hydrogen evolution reaction (HER). New etching parameters are proposed to obtain Nb4C3Tx with the largest c-lattice constant (3.165 nm) to date. Notably, Nb4C3Tx shows higher catalytic activity under the alkaline condition. Consequently, Nb4C3Tx has an overpotential of 398 mV at a current density of 10 mA cm(-2), which is considerably less than that of other reported MXenes. Moreover, Nb4C3Tx has superior cycling performance and long-term stability in both acidic and alkaline environments. After 1000 cycles of CV, the overpotential of Nb4C3Tx clearly decreased by approximately 30 mV, and the current density significantly increased after the timing current test up to 50 h. This work demonstrates the excellent electrochemical performance that Nb4C3Tx can provide to benefit broad application prospects in energy fields. (C) 2020 Hydrogen Energy Publications LLC.
