Abstract null null High-performance microwave absorption materials with strong absorption and thin thickness have increasingly become a reach hotspot. Here, we successfully prepared a novel porous hollow Co/C microcube by controlling the pyrolysis of the Co-based metal-organic frameworks (MOFs) precursor. The phase composition, microstructure, porosity, and magnetic properties were well modified by controlling the pyrolysis temperature. The multiple components (Co and C) and novel porous structu...

Abstract null null Searching for electromagnetic wave (EMW) absorbers with high-efficient absorption and multi-functionalization is very eager to satisfy modern society’s technical requirements. Inspired by nature, popcorn-derived honeycomb-like NiS2/SnS2 nanosheets @ 3D porous carbon hybrids (PC-NSS) were fabricated through hydrothermal and carbonization methods. As multifunctional electromagnetic wave absorption (EMA) materials, PC-NSS exhibited preeminent infrared stealth property, thermal in...

Abstract null null Metal-organic frameworks (MOFs) derived metal/carbon composites are considered as feasible high-performance electromagnetic wave absorption materials and have received considerable attention. Herein, biconical prisms Ni@C composites were fabricated via a simple carbonization of Ni-MOFs template. It was found that the core-shell biconical prisms Ni@C composites achieved an optimization of the impedance matching and an efficient microwave absorption performance by regulating the...

Abstract null null At present, the development of lightweight and wideband microwave absorbing materials with stable infrared stealth property and adaptable to complex environments has become the key to multi-modal stealth technology. Herein, hollow CuS microflowers were self-assembled on biomass-derived porous carbon in situ to realize the multifunctions of microwave absorption, flame retardance and thermal stealth. The multicomponent synergistic effect combined with unique microarchitecture tr...

ABSTRACT Metal-organic frameworks (MOFs) derived carbon-based magnetic metal materials had attracted much attention in the field of electromagnetic wave absorbers. In this work, a layered FeCo@C nanocomposites was successfully synthesized by annealing FeCo-MOFs. The pyrolytic temperatures had influenced the graphitization degree of the carbon frameworks and the magnetic properties of the FeCo nanoparticles. Owing to the outstanding attenuation capacity, impedance matching and unique layered stru...

Abstract null null Developing high-efficiency electromagnetic wave absorption materials with versatility has been a hotspot and it remains a huge challenge. Here, we reported versatile laminated Ni nanoparticles @ porous carbon (Ni@C) nanocomposites synthesized by a facile carbonization of Ni-based metal-organic frameworks (MOFs) precursor. It was found that the phase components (Ni and C phases) and nano/microstructure (laminated and porous characterizations) were well-modified by controlling t...

Abstract null null The morphology modulation of multi-level structures and the multifunctional design of their composites are challenging research priorities in the field of electromagnetic wave absorption. In this work, the abandoned polyurethane is adopted as a sacrificial template of a three-dimensional carbon network. The morphology-controlled Fe/Fe2O3@porous carbon composites with highly cross-linked 3D structures are synthesized by simple hydrothermal and thermal treatments. Among them, th...
