The unique α-Fe2O3 hexagonal nanosheets have been successfully prepared through a facile solvothermal method with subsequent calcining process. The as-synthesized α-Fe2O3 sample exhibits p-type conductive performance. The gas sensitivities of the as-fabricated Fe2O3 nanosheets-based sensor are comprehensively studied and show good gas-sensing performance toward aniline. Furthermore, the aniline-sensing mechanism is investigated and the origin of the p-type conductivities is also discussed.
