“…The PCN-224 (Fe)-2 and PCN-224 (Fe) show the quasi-hexahedron particles with particle sizes in the 200–400 nm range (Figures S3 and S4). The formation of more regular spherical morphology of the PCN-224 (Fe)-1 may be because the amphiphilic octylpyridine group acted as a surfactant during the growth of the MOF . As shown in Figure e, the elemental-mapping spectrum shows that Fe and N are clearly dispersed in the PCN-224 (Fe)-1, with the contents of 1.7 at% (Fe) and 8.5 at% (N), respectively (Figure S5 and Table S1).…”

Herein, the "push effect" strategy combined with "triple-phase-boundary" (TPB) engineering was innovatively employed to target the single Fe−N 4 sites in an iron porphyrinbased metal−organic framework, with axially coordinated 4octylpyridine groups on Fe−N 4 (named as PCN-224 (Fe)-1). The amphiphilic 4-octylpyridine groups donate sufficient electrons toward Fe−N 4 by the Fe−N(pyridine) coordination bond and simultaneously provide effective TBP reactive sites by the hydrophobic octyl terminals, resulting in enhanced ORR activity of the PCN-224 (Fe)-1 in hydrophobic octyl terminals, with an E 1/2 of 0.81 V and complete 4-electron selectivity. Furthermore, TPB engineering is utilized to construct the PCN-224 (Fe)-1based Zn−air battery with a maximum power density of 98 mW cm −2 , demonstrating great practical application potential for molecule-based ORR catalysts. Meanwhile, the "push effect" mechanism on ORR is revealed by electron paramagnetic resonance, in situ UV−vis spectroelectrochemical analysis, and density functional theory.

“…Cyt c is a relatively large, structurally robust heme protein molecule with molecular dimensions of 2.6 nm × 3.2 nm × 3.3 nm, and its size is compatible with immobilization in H-mMOF-1. [39][40][41] The enzyme immobilization performance and its effect on the catalytic activity of H-mMOF-1 were studied. After the enzyme was immobilized in the mesopores, medi-MOF-1 and Cyt c worked together to greatly improve the catalytic activity.…”

Molybdenum carbide (MoC) integrated into a carbon matrix, known for its robust interfacial polarization, emerges as a promising ultra‐lightweight EM wave absorber. However, the fabrication of such materials remains a formidable challenge. Herein, a facile and scalable strategy for preparing MoC‐incorporated carbon matrix employing ZnMo‐HZIF foam material through ball‐milling foaming and calcination process as a promising electromagnetic wave materials (EWAMs). In detail, the 3D foam structure reaches impedance matching, and heterogeneous interfaces of N‐doped MoC‐incorporated carbon material (MoC/NC) promote the dipolar/interfacial polarization, confirmed by the hologram. Mo defects induced the charge transfers, displaying an enhanced interfacial polarization. At 15 wt.%, the minimum reflection loss of the obtained sample at 2.5 mm reaches −47.56 dB, and the effective absorption bandwidth spans 4.40 GHz, nearly covering the full X band. Additionally, the assembly device testing demonstrates their excellent self‐cleaning, heat‐insulation, flame retardancy, and infrared stealth properties. This work presents a new perspective on the synergistic effect of structure and components on electromagnetic wave absorption performance and provides a new approach for preparing lightweight and high‐performance MOF‐based electromagnetic wave absorbing materials.
