Abstract
A simple solvent thermal method and subsequent annealing process were adopted in the successful synthesis of In2O3 nanocuboids. Outstanding sensing performance is demonstrated in the prepared In2O3-based sensor including relative low working temperature (180 °C) and high response value ∼30 toward 20 ppm triethylamine. Excellent triethylamine sensor performance is due to the unique configuration of nanocuboids and a large number of oxygen vacancies in In2O3 nanocrystals, thus improving gas sensitivity. Furthermore, the triethylamine sensing mechanism and potential growth mechanism are also studied.
