英文摘要	Nanosheet-based three-dimensional (3D) hierarchical rosette-like In2O3 microspheres and hollow microspheres are successfully prepared by a hydrothermal and subsequent annealing process. The formation mechanism of In(OH)(3)(En)(2) microsphere precursors is investigated systematically, and the possible chemical reactions at each stage are proposed. The complexing agent and the surfactant are the two important factors to control the morphologies and microstructures of the final products. The as-synthesized hierarchical In2O3 microspheres show excellent sensing response to volatile organic compounds such as acetone and toluene gases. The detection limit can be as low as similar to 500 ppb level in atmosphere. In addition, the sensing mechanism based on the change of surface resistance is discussed. Such novel In2O3 microspheres may be a promising candidate for sensor application in detecting acetone or toluene in different environments. (c) 2013 Elsevier B.V. All rights reserved.
