In2O3 nanostructures: synthesis and chlorobenzene sensing properties

In this work, In2O3 nanorods and nanoparticles have been successfully prepared by solvothermal methods followed by annealing of the precursors at 300 °C. Experimental results show that the morphology and phase are strongly influenced by the solvents used. Moreover, we have developed gas sensors based on ultrathin In2O3 nanorods, which demonstrate excellent o-dichlorobenzene and chlorobenzene sensing properties, superior to those of nanoparticles with a similar size. It is expected that our as-synthesized In2O3 nanorods could potentially be applied in real-time monitoring of polychlorobenzene concentrations in the future.
