Article Abstract
Microwave absorbing materials (MAM) have attracted considerable attention over the years in stealth and information technologies. Metal-organic framework (MOF) with a unique microstructure and electronic state has become an attractive focus as self-sacrificing precursors of microwave absorbers. The MOF-derived porous carbon (PC) materials exhibit a high absorbing performance due to the stable three-dimensional structure and homogeneous distribution of metal particles. MOF-derived PC materials are promising for ideal MAM tuning of the structure and composition, resulting in appropriate impedance matching and the synergistic effect between magnetic and dielectric loss. In this review, the MOF-derived PC materials and their basic absorption mechanisms (dielectric loss, magnetic loss and impedance matching) are introduced, as well as the characters of various MOF-derived PC materials. In addition, this review provides a comprehensive introduction and tabulates the recent progress based on the classification of the MOF-derived metallic state, such as pure PC (without reduced metals), mono-metal/PC, multi-metal/PC, metal oxides/PC and other derived PC composites. Finally, the challenges faced by MOF-derived PC materials are overviewed, and their further development is mentioned.

Overcoming the persistent challenges of high operating temperatures and poor selectivity in metal oxide semiconductor (MOS) gas sensors, this work enhances defect sites in the sensing material through heterostructure construction and builds mesoporous architectures using MOF-derived carbon skeletons as templates. The synergistic effects of multiple mechanisms significantly improve gas-sensing performance, successfully fabricating a ZnO/PCS flexible room-temperature gas sensor with exceptional room-temperature DMF detection capabilities. The nitrogen-containing porous carbon skeletons (PCSs) template shows a stable mesoporous microstructure with large pore volume.

Integrating cross-scale active sites-single atoms (SA), atom pairs (AP), and nanoparticles-into a unified catalytic system presents a promising strategy for advancing oxygen reduction reaction (ORR), an extremely important process in energy conversion. However, the synergistic interplay among these sites and their mechanistic roles remains poorly understood. Here, we report a novel catalyst (3) featuring Zn, bonded Fe-Co with dual-oxygen ligands, and FeCo nanoparticles, synthesized via pyrolysis of a metal matrix-engineered metal-organic framework (MOF).

Precise regulation of self-reconstruction in metal-organic frameworks (MOFs) presents a promising strategy for designing high-performance oxygen evolution reaction (OER) electrocatalysts. In this study, we introduce an amorphization strategy to induce profound self-reconstruction in bimetallic tetrathiafulvalene tetrabenzoate (HTTFTB) MOFs supported on nickel foam (NF). The optimized CoFe-TTFTB@NF electrocatalyst exhibits remarkably low overpotentials (228 mV at 10 mA cm, 267 mV at 100 mA cm) and maintains stability for 200 h at 100 mA cm, outperforming commercial RuO and most reported MOF-based catalysts.

Ni@carbon nanoframework-multi-walled carbon nanotubes (Ni@CNF-CNTs) nanomaterials were synthesized through the carbonization of flower-like nickel metal organic framework (Ni-MOF) and multi-walled carbon nanotubes (MWCNTs). Subsequently, a high-performance flutamide (FLT) - an anti-androgen drug - electrochemical sensor was constructed using the nanomaterials. Both Ni@carbon nanoframework (Ni@CNF) and MWCNTs have adsorption capacity for FLT.
