▎ 摘　　要

Herein, the iron ions doped tin dioxide/reduced graphene oxide (Fe-doped SnO2/RGO) nanocomposites were fabricated by a facile one-step hydrothermal strategy. The structure, composition, micromorphology, and electromagnetic parameters of the obtained nanocomposites were systematically investigated by various analysis techniques. Results revealed that the doping of Fe3+ ion had notable effect on the structure and electromagnetic wave (EMW) absorption properties of SnO2/RGO nanocomposites. The as-prepared Fe-doped SnO2/RGO nanocomposites showed the minimum reflection loss (RLmin) of -29.0 dB and effective absorption bandwidth (EAB, RL
