摘要：

Porous In2O3 nanocuboids were synthesized successfully on a large scale and characterized with XRD, TG-DTA, BET, FESEM and TEM. The precursors - In(OH)(3) nanocuboids, which were first produced in the nanoreactors consisting of sodium bis(2-ethylhexyl) sulfosuccinate (AOT) surfactant and In3+ ions, can transform topotactically to form porous In2O3 nanocuboids, after annealed at 300 degrees C. The gas sensing performances of the materials were also investigated before and after modified with Pd nanoparticles. The chemical sensors made with Pd@In2O3 nanocuboids exhibit enhanced performances in detecting reducing gases such as acetone, compared to those fabricated with pure porous In2O3 nanocuboids.
