Abstract

In this work, porous indium oxide is synthesized by hydrothermal method. The In₂O₃ has been structurally and optically characterized by using XRD, XPS, FESEM and TEM techniques. The morphological studies have revealed the growth of self-assembled In₂O₃ nanoparticles which helpts to form a brick-like structure. The porous In₂O₃ nanoparticles have provided the large number of active sites for the adsorption of gas molecules which resulted in a quick sensor response of 6877 for 10 ppm of NO₂ gas at very low temperature of 50 °C. Remarkably, the In₂O₃ sensor has shown the detection of NO₂ gas down to 60 ppb.
