In this study, a facile one-step hydrothermal method was used to fabricate Mo2CTx-N with superior advantages. The synergistic effects of pillared structure, immobilizing -F groups and unlocking Mo-based redox contributed to its excellent reversible capacity.
Inspired by a well-known architecture notion that load-bearing walls enable maintaining a highly-stable multiple-floored building, superior advantages are afforded via fabricating the NH4+ ions pre-intercalated Mo2CTx MXene (Mo2CTx-N) in a mixed solution of NH4F and HCl via a simple one-step hydrothermal method. As a result of the synergistic effects of pillared structure, immobilizing -F groups and unlocking Mo-based redox, the Mo2CTx-N remarkably delivered a reversible capacity of 384.6 mAh g(-1) at 200 mA g(-1) after 100 cycles. Our work lays a foundation for fully packaging its optimal performance via carding and architecting the chemistry of the MXene layers and between them.
