Abstract in another language

An indium trioxide (In2O3) nanoparticle based conductometric sensor has been fabricated and tested towards NO2 gas. Novel chemical synthesis method was developed, in which benzylamine was mixed with indium acetate to form In(OH)3 as a precursor to form In2O3. Microcharacterization results revealed that the average size of the In2O3 nanoparticles is 8 nm and the particles have a cubic crystalline phase. Sensors exhibited very high sensitivities towards NO2 at an operating temperature of 150°C. Fast response and recovery with good repeatability along with stable baseline were observed.
