“…Compared with pristine MOFs, MOF derivatives usually possess higher chemical stability, stronger light harvesting and charge transfer ability, and thus have been considered a promising class of photocatalysts. 113,114 Naturally, the design of MOF-derived S-scheme heterojunctions has also witnessed great advances. 115,116 For example, S-scheme In 2 O 3 /ZnO nanotubes were synthesized by using ln-MIL-68 as the precursor through a two-step annealing immersion process, as illustrated in Fig.…”

“…Cui et al designed a composite made of rGO, Nb 2 CT x , and Fe 3 O 4 that exhibited excellent electromagnetic wave absorption with an RL min of −59.17 dB at a thickness of 2.5 mm and simultaneously attained a wide EAB of 6.8 GHz . Notably, the flexible crystal pore size, changeable element types, and regular morphology of metal–organic frameworks (MOFs) provide inherent advantages that make them a viable option as precursors for the production of magnetic metals. − The MOFs containing magnetic metal ion-derived metal/carbon nanocomposites show both magnetic loss and electric dielectric loss, which provide multiple ways for the dissipation of electromagnetic waves. − However, there are few works on the fabrication of EMA materials using MXene, rGO, and MOF-derived materials.…”

Efficient electromagnetic wave absorption (EMA) materials are urgently needed to solve the increasingly serious electromagnetic pollution problems in both the modern military and civil fields. Multidimensional and multielement electromagnetic absorbing materials exhibit enormous potential in EMA applications owing to the combination of material and structure advantages. Herein, a three-dimensional (3D) reduced graphene oxide/Ti 3 C 2 T x MXene/iron−cobalt alloy carbon (rGO/MXene/FeCoC) nanocomposite aerogel derived from FeCo-ZIF metal−organic frameworks (MOFs) was successfully fabricated by combining freezedrying and pyrolysis methods. The minimum reflection loss (RL min ) of the optimized rGO/MXene/FeCoC-30% is −61.4 dB and the effective absorption band (EAB, <−10 dB) reaches up to 4.95 GHz with a matching thickness of 1.55 mm. The outstanding EMA performance benefits the excellent impedance matching, the rich multiple reflections and scattering in three-dimensional porous structures, and the favorable dielectric-magnetic synergistic losses endowed by graphene, MXene, and FeCoC nanoparticles. The successful construction of the multicomponent rGO/MXene/FeCoC nanocomposite aerogel provides a prospective direction for the development of high-efficient electromagnetic absorbing materials.

“…10,11 In general, due to favorable porosity and semiconductor properties, pristine MOFs are commonly applied in the fields of adsorption, gas separation and photocatalysis. 12,13 In recent years, the preparation of metal/carbon nanocomposites using metal–organic framework (MOF) materials as starting templates has received widespread attention on account of their highly tunable microstructures and elemental compositions, 14,15 mainly regarding energy storage, 16 electrocatalysis 17 and batteries. 18 Importantly, these customizable MOF-based derivatives also demonstrated prominent advantages in the high-performance microwave absorption materials field.…”
