The antibacterial activity of g-C3N4 and Cu-g-C3N4 was evaluated against E. coli, with their disinfection capabilities influenced by structural characteristics, photocatalytic properties, modulation under a static magnetic field. incorporation Cu2+ does not significantly affect the (210) reflection in XRD analysis, indicating that alignment aromatic layers remains stable. However, presence copper enables complete disinfection, contrast to graphitic carbon nitride, which achieves only partial disinfection. is likely positioned at N-aliphatic sites coexists hydroxylated species, may influence performance modifying reactant adsorption ROS generation. SEM-EDS analysis confirmed modification did alter material’s morphology, although 3% content detected, suggesting heterogeneous surface distribution. Thermodynamic showed exposure field increased Gibbs free energy from 6.34 J/m2 10.52 J/m2, reducing interactions key reactants essential for formation. As result, both photodegradation efficiency were diminished. Additionally, found modify properties material, affecting its performance. In Cu-C3N4 materials, decrease contact angle suggests enhanced hydrophilicity, while an increase tension water hydroxyl radicals. This study underscores effect on behavior materials deposited polymeric substrates intrinsic electronic ultimately impacting overall efficiency.

Abstract In response to mitigating the severe shuttle effect within lithium–sulfur batteries, single‐atom catalysts have emerged as one of most effective solutions. Here, N, F, B codoped porous hollow carbon nanocages (NFB‐NiFe@NC) with high Ni and Fe doping are rationally designed synthesized using ionic liquids (ILs) dopants. The introduction ILs inhibits growth zeolitic imidazolate framework‐8 (ZIF8), resulting in NFB‐ZIF8 precursors smaller particle sizes, enabling higher loading dual‐atom catalysts. Meanwhile, abundant heteroatoms increase reactive sites alter matrix's nonpolar intrinsic properties, thus enhancing chemisorption polysulfides. synergistic interaction dual‐atoms ultimately promotes catalytic conversion kinetics As a result these beneficial cells prepared NFB‐NiFe@NC modified separator exhibit significantly improved performance, including initial capacity 1448 mAh g −1 at 0.2 C. Even S‐loading 7.6 mg cm −2 , ideal area 8.38 can still be maintained 0.1 New insights provided here for designing highly loaded application batteries.
