چکیده انگلیسی
Porous In2O3 nanoparticles with sizes ranging from 20 to 50â¯nm were successfully prepared using a solvothermal method. The phase structure and morphology of the In2O3 samples were characterized using X-ray powder diffraction and scanning electron microscopy, respectively. Brunauer-Emmett-Teller analysis revealed that the obtained optimal In2O3 nanoparticles were porous with a large surface area of 108.77â¯m2/g. Incorporated into a ceramic tube gas sensor, the In2O3 nanoparticles acted as a gas-sensing material for n-butanol. The sensor performed well, including a high response, short response and recovery times, good selectivity, and good reproducibility and stability to n-butanol gas at a working temperature of 140â¯Â°C. These porous In2O3 nanoparticles thus show potential for use as gas-sensing materials to monitor the concentration of n-butanol gas.
