| Abstract: | Functional carbon nanomaterials have become the stars of many active research fields, such as electronics, energy, catalysis, imaging, sensing and biomedicine. Herein, a facile and one-pot strategy for generating ferromagnetic nanoparticles loaded on N-doped carbon nanosheets (Fe-N-CNS) is presented by salt-assisted high-temperature carbonization of natural silk proteins. Due to their graphitic structures, N-doping and ferromagnetic nanoparticles (FeNx, FeOy, FeCz), the silk-derived Fe-N-CNS can act as excellent mimics of both peroxidase and oxidase. Benefiting from the combined character of the graphene-like structures and enzyme-like activities, Fe-N-CNS can be further applied to highly efficient dye removal via synergistic adsorption and degradation. Meanwhile, the as-prepared Fe-N-CNS with intrinsic magnetism and electrical conductivity can also serve as an efficient electromagnetic wave absorption agent. The broadest effective absorption bandwidth (EAB) of as-obtained absorbing material yields a 6.73 GHz with 1 mm thickness, with a maximum reflection loss of −37.33 dB (11.41 GHz). The EAB can cover 2∼18 GHz with a tunable absorber thickness from 1.0 mm to 5.0 mm. Collectively, Fe-N-CNS, as a dual-functional material, can tackle the aggravating environmental pollution issues of both dyes and electromagnetic waves. |
