The preparation of a MoSi₂ antioxidant coating is an effective method for improving the protective ability of refractory metals at high temperatures. However, although MoSi₂ coatings have many advantages, it is difficult to meet the increasingly stringent service requirements. To address these challenges, researchers have used different elements to modify a single MoSi₂ coating and improve its overall oxidation resistance. In this study, the roles of one or more elements (Si, B, N, Zr, Al, W, Hf, Y, Ti and Cr) in MoSi₂ coatings are systematically reviewed. Simultaneously, the mechanism of single or multiple synergistic modification of MoSi₂ coatings with different elements was discussed.

However, single-component catalysts often cannot handle the multiple kinetic steps during hydrogen production. To address this challenge, a heterogeneous catalyst comprising metal Co, CoO and carbon-doped Mo₂N (Co–CoO–C/Mo₂N/CC) was synthesized by heat treatment of carbon cloth-supported CoMoO₄ microrods in a mixed reduction atmosphere. The resulting catalyst has rich interfaces, exhibiting excellent initial HER activity with an overpotential of 27 mV at 10 mA·cm⁻² and a Tafel slope of 37 mV·dec⁻¹. Further studies show that the activity and stability of the catalyst can be tailored by the dynamic surface reconfiguration and doping effects. The carbon doping and high crystallinity in Mo₂N help to reduce the dissolution of Mo and the surface metal Co is preferentially converted into stable Co(OH)₂, thus stabilizing the structure of the catalyst and coordinating various reaction kinetics. In an electrolyzer comprising a heterogeneous Co–CoO–C/Mo₂N cathode and NiFe layered double hydroxides (LDH) anode, only 1.58 V is required to achieve a current density of 50 mA·cm⁻², outperforming Pt/RuO catalysts. After continuous electrolysis for 100 h, the potential increases by merely 19 mV from the initial 1.58 V, indicating excellent stability.

A variety of coal-derived carbon materials have been constructed using different strategies and have been investigated for diverse electrochemical energy storage due to their specific microstructures. In the short term, the electrochemical performance of coal-derived carbon materials is normal. However, it is imperative to develop low-cost and high-performance coal-derived carbon materials in order to reduce the cost of energy storage systems. Therefore, this review focuses on the microstructure modulation strategies for coal-based derived carbon materials to further enhance their electrochemical performance through heteroatom doping, defect engineering, interlayer engineering, crystallinity regulation, pore regulation and multi-strategy synergy. In addition, this review summarizes the enhancement mechanisms for modification strategies and analyses their limitations. Furthermore, current challenges and future research directions for the development of high-performance coal-based derived carbon materials are proposed in this review.

However, the effects of transition metals doping on its magnetic properties, detailed atomic occupancy and the mechanism for structural stability remain unclear. Specifically, for SmCo₃ magnets, there is minimal theoretical study available. Herein, based on first-principles calculations, we systematically investigated the influence of 3d transition metals (TMs) doping on the structural stability, magnetic properties and electronic characteristics of SmCo₃ magnets. Our results show that Sc, Ti, V, Fe, Ni, Cu and Zn preferentially occupy the 18h lattice site, while Cr and Mn occupy the 3b and 6c lattice sites, respectively. Doping with Ti, Cr, Mn, Fe, Ni, Cu and Zn contributes to enhancing the stability of SmCo₃, whereas the doping of Sc and V adversely affects structural stability. The magnetic calculations reveal that Cr, Mn and Fe doping significantly enhances the total magnetic moment. It is also found that lower concentrations of Cr doping can significantly enhance the magnetocrystalline anisotropy energy (MAE). More intriguingly, when the doping concentrations of Sc, Ni and Cu reach 14.81 at%, 22.22 at% and 22.22 at%, respectively, the magnetic easy axis of the system shifts from out-of-plane to in-plane. The optimal doping concentration of Fe in the SmCo₃ system is determined to be 37.04 at%. The Curie temperature of pure SmCo₃ is 483.9 K.
