Summary: Constructing a unique electrochemical interface using platinum-analogous molybdenum carbide (Mo2C) with a lower content of platinum (Pt) is essential for enhancing the catalytic capacity of Pt-based catalysts for the hydrogen evolution reaction (HER). The Pt/Mo2C (C) heterostructure was successfully constructed using a solid-phase method, resulting in significantly improved HER activity and long-term durability in an acidic medium. The obtained Pt/Mo2C (C) exhibited a low overpotential and a high H-2 production rate, making it a promising material for efficient HER.

Summary: We demonstrate that an ordered 2D perovskite can significantly enhance the photoelectric performance of 2D/3D perovskite heterostructures. By selectively fluorinating phenyl-ethyl ammonium (PEA) lead iodide to passivate 3D FA(0.8)Cs(0.2)PbI(3), we find that the 2D/3D perovskite heterostructures passivated by a higher ordered 2D perovskite exhibit lower Urbach energy, resulting in a remarkable increase in photoluminescence (PL) intensity, PL lifetime, charge-carrier mobilities (ϕμ), and carrier diffusion length (L-D).

Summary: Recent studies have shown that bimetallic carbide, due to its abundant active sites, high conductivity, and electrochemical stability, is a promising electrode material for supercapacitors. By combining bimetallic carbides with other advanced materials such as graphene, porous carbon, or carbon nanotubes (CNTs), the electrochemical properties of the electrode can be greatly enhanced. In this study, Fe3Mo3C/Mo2C@CNTs composite material was synthesized for the first time using hydrothermal and high-temperature carbonization methods. The Fe3Mo3C/Mo2C@CNTs nanoparticles carbonized at 800℃ exhibited the best electrochemical performance, with a specific capacitance of 196.3 F g-1 at a scanning rate of 10 mV s-1 (202.3 F g-1 at 1 A g-1). An asymmetric supercapacitor assembled with Fe3Mo3C/Mo2C@CNTs and NiCo2O4 electrode achieved an energy density of 39.9 Wh Kg-1 at a power density of 1800 W Kg-1, with a capacitance retention rate of 73.9% after 4000 cycles. Overall, Fe3Mo3C/Mo2C@CNTs shows significant potential as a negative electrode material for supercapacitors in the field of electrochemical energy storage.

Summary: Based on first-principles calculations and theoretical analysis, we demonstrate that large Berry curvature dipoles and Ising superconductivity can coexist in monolayer MXene heterostructures of T-Mo2C/H-Mo2C. The large Berry curvature dipoles result from multiple band anticrossings and band inversions near the Fermi level. The breaking of in-plane space-inversion symmetry in these 2D superconductors induces Ising-type spin-orbit coupling, and one of the heterostructures is identified as a Z2 topological metal.

Summary: This study proposes a field-effect spin filter based on a two-dimensional antiferromagnetic/ferromagnetic vdW heterostructure MnPS3/MnCl3. The heterostructure exhibits antiferromagnetic-ferromagnetic transition and semiconductor-metal-half-metal transitions when the interlayer distance is reduced to d<2.0 angstrom. A semiconductor-half-metal transition can also be achieved by applying an external electric field. This study offers a potential approach for designing spintronic devices using two-dimensional magnetic vdW heterostructures.
