Summary: In this study, a novel metallic heterostructure composed of defect-rich nickel and amorphous/crystalline molybdenum nitride anchored on a carbon matrix (MoN/Ni@C) was fabricated and demonstrated as a superior electrocatalyst for the hydrogen evolution reaction (HER). The MoN/Ni@C electrocatalyst exhibited low HER overpotential and small Tafel slope, along with excellent stability in alkaline solution. Density functional theory calculations revealed that the interfacial electron transfer contributed to the distortion of Ni surface and the optimal thermoneutral hydrogen adsorption free energies on Mo and Ni active sites. The amorphous/crystalline structure in the MoN phase provided more active sites and promoted structural stability. This work provides new insights into designing non-noble-metal-based electrocatalysts with superior HER activities.

Summary: In this study, a type of two-dimensional ferromagnetic material called Janus TiXY is predicted through systematic first-principles calculations. These materials exhibit spin ordering above room temperature and diverse electronic structures. The research demonstrates the transition of band gaps and spin splitting in these materials by flipping the spin direction. Furthermore, the interlayer magnetic coupling can be controlled by stacking configurations, and the intrinsic electronic properties can be maintained by applying a protective graphene layer. These findings make Janus TiXY monolayers promising candidates for practical spintronic applications and open up new avenues for designing novel two-dimensional ferromagnetic materials based on non-magnetic materials.
