Microwave absorption and solar evaporation have attracted significant interests and great advances have been achieved in the elimination of electromagnetic radiation pollution and production of fresh water. However; enhancing low-frequency microwave absorption properties as well as mass production of cheap solar evaporators with high evaporation rate are still facing many challenges. Herein; γ-Fe2O3 nanocubes/graphene (GFC) composites were prepared by a facile one-step solvothermal method. GFC was mixed with paraffin to study its microwave absorption properties. The minimum reflection loss (RL) value of -59.3 dB at 2.4 GHz was achieved by GFC; while the RL value also reached -57.2 dB at 5.12 GHz with a thickness of 5.30 mm. Moreover; under matching frequency and thickness a good absorption performance (RL ≤ -17.2 dB) from 2.00 to 18.00 GHz was obtained; in particular; RL 97% absorption in entire solar spectrum range. Its evaporation rate (3.490 kg m-2h−1) is 5.1 times larger than that of pure water under the same condition; which shows great potential applications in desalination; water purification and energy generation. © 2020 Elsevier B.V;
