Abstract The nitrogen‐rich molybdenum nitrides (N/Mo > 1) are promising for water electrolysis due to their increased activity and antioxidant ability. However, a higher temperature is needed in the usual synthesis introducing more N, leading formation of large particles difficulty controlling morphology, thus limiting catalytic performance. Here, new strategy reported based on synergy internal/external N sources (INS ENS) toward Mo 5 6 ‐based catalysts at decreased 450 °C. PMo 12 clusters Ni 2+ (Co ) first combined with 2‐methylimidazole/melamine (INS) give flower‐like assembly. subsequent pyrolysis under NH 3 flow (ENS) gives flowers composed small /Ni (Co) heterojunctional that can expose surface sites an optimized electronic structure. exhibits good HER close Pt/C, /Co shows superior OER performance IrO 2 . /Ni||Mo cell drives overall splitting (OWS) low voltage 1.397/1.74 V achieve current density 10/100 mA cm −2 1.0 M KOH.

Abstract 2,5‐Furandicarboxylic acid (FDCA) has emerged as an important bio‐based furanic compound, which broad application prospects in renewable energy and materials, especially the preparation of polyethylene 2,5‐furandicarboxylate (PEF). While conventional synthesis FDCA involves oxidation 5‐hydroxymethylfurfural (HMF) a substitute, thermal chemical instability HMF due to its aldehyde group poses challenges. A more favorable alternative is utilization 2,5‐bis(hydroxymethyl)furan (BHMF), non‐aldehyde stable precursor. This study pioneeringly reports nitrogen‐doped‐carbon encapsulated cobalt (Co@NC) chainmail nanowires for electrocatalytic BHMF FDCA. The Co@NC/NF achieved 97.9 % conversion with 93.3 yield at 1.475 V vs. RHE, whereas catalysis only obtained 14.9 after 10 hours. Kinetic studies indicated that large electrochemically active surface area excellent kinetic parameters contribute superior electrochemical performance. Mechanistic analysis revealed migration inner electrons exterior modified electronic properties carbon layer, thereby facilitating BHMF. Furthermore, in‐situ generation high‐valent species markedly accelerated oxidation. research underscores potential carbon‐encapsulated metal catalysts biomass conversion.

Abstract MXenes, a class of two‐dimensional (2D) transition metal carbides, and covalent organic frameworks (COFs) deliver unique structural electrochemical properties, making them promising candidates for energy storage conversion applications. MXenes exhibit excellent conductivity tunable surface chemistries, whereas the COFs provide high porosity versatility. Recent advances in integrating MXene‐COF composites have revealed their potential to enhance charge transfer storage/conversion properties. The work highlights key developments integration, offering insights into applications batteries (Li‐ion, K‐ion, Na‐ion, Li‐S), supercapacitors, electrocatalysis (HER, OER, RR, NRR, ORRCO2), while also addressing current challenges future directions not only but other electronic devices. image
