 X-ray diffraction revealed that the Xeno particles had a word-site crystal structure with an average diameter of 51 to 66 nanometers, while the iron oxide particles on the Xeno surface had a hematite crystal structure and an average diameter of 23 to 28 nanometers. Energy dispersive spectroscopy showed that the films contained 1.3 to 5.8% iron. Optical studies indicated that the films had an optical band gap of 3.16 to 3.26 EV. Gas sensing tests conducted at temperatures ranging from 150 degrees Celsius to 300 degrees Celsius demonstrated that the films exhibited high responses to 100 ppm acetone and ethanol as well as a high and selective response to 300,000 parts per billion of nitric oxide. Additionally, the film's ability to detect nitric oxide was not affected by humid. This article was authored by Artem S. Mokrishan, Yulia M. Gorbin, Alexei Avron, and others. We are article.tv.
