Single-step controllable preparation and gas sensing performance application of claw-like indium oxide

In recent years, researchers attach great importance to the detection methods and materials of polluting gases, and there have been many detection of sensitive materials of different MOS (Metal oxide Semiconductor). In our work, the claw-like indium oxide material was synthesized by a single-step controllable environment-friendly method. The samples were characterized by TG, XRD, FESEM and TEM. These experimental results indicate that the synthesized sample consists of irregular nanorods with uneven surface, which were similar to claws. In addition, gas properties of claw-like In2O3 were studied, and the detection limit was up to 20 ppb, which was more significant response to nitrogen dioxide than other gases.
