Abstract
The ionic liquid precursor tetrabutylammonium hydroxide (TBAH) is used to synthesize In(OH)3 particles. The ionic liquid TBAH is demonstrated to be effective for the synthesis of In(OH)3 nanorods with a controlled size. The effect of the indium salt and the added water amount on the final products is investigated. The synthesized In(OH)3 nanorods could be further transformed into porous In2O3 rod particles. Specifically, the gas sensing properties of the synthesized porous In2O3 rod particles to various organic compounds (methanol, ethanol, isopropanol, butanol, ethyl acetate and toluene) exhibit remarkable sensitivities, low detection limits and fast response–recovery times, which are superior to the reported In2O3 based sensors. The as-prepared porous In2O3 rod-based sensors thus demonstrate their potential applications in detecting chemical contaminants and dangerous gases.Keywords
