Biphasic Ni-MXene Quantum-Confined Nanostructures: A Versatile Janus Platform for Advanced Energy Storage and Catalytic Oxidations.

ABSTRACT: The demand for sustainable energy storage and ecofriendly catalysts has intensified the search for advanced multifunctional materials. Herein, this work presents the synthesis and characterization of Janus Ni-MXene quantum dot (Ni-MJQD), a novel material architecture that exhibits high performance in supercapacitor and catalytic applications. A Ni-MJQD cathode delivers an impressive gravimetric specific capacity of 168.75 mAh g^-1 at 3 A g^-1, and its Janus structure optimizes the balance between capacity and ion diffusion. In an asymmetric hybrid supercapacitor (AHSC) with a porous activated carbon (PAC) anode, it achieves an energy density of 54.22 Wh kg^-1, a power density of 1599 W kg^-1, and 88% capacity retention over 20 000 cycles. As a cataly
