摘要：
Hexagonal In2O3 microspheres, Cubic In2O3 porous nanoparticles, and cubic In2O3 porous nanorectangles were fabricated by calcining precursors at 450 C, respectively. The precursors InOOH microspheres, In(OH)(3), nanoparticles, and In(OH)(3) nanorectangles were solvothermally synthesized by adjusting the volume ratios of ethylenediamine and distilled water in a autoclave 160 C. Gas-sensing properties determination of ethanol, formaldehyde. and ammonia gases show that the cubic In2O3 porous nanoparticles have a higher response than the hexagonal In2O3 microspores (c) 2008 Elsevier B.V.
