Synthesis and characterization of ErFeO3 nanoparticles by a hydrothermal method for isopropanol sensing properties

Construction of Flower-like PtOx@ZnO/In2O3 Hollow Microspheres for Ultrasensitive and Rapid Trace Detection of Isopropanol

“…Table exhibits the comparison of the isopropanol sensing performance of our Pt@ZnIn 2 sensor with that of other SMO-based isopropanol sensors in previous studies. It can be clearly seen that our Pt@ZnIn 2 sensor outperforms most of the previously reported isopropanol sensors in terms of response, LOD, response/recovery speed, and linearity range, ,,,− which means that it is a great potential candidate for trace isopropanol detection under relatively dry and ultrahumid atmospheres.…”

Synthesis and characterization of ZrO2–ZnO heterojunction composite for isopropanol detection

“…Isopropanol belongs to the category of volatile organic compounds(VOC), which is an organic, colorless, and flammable liquid. 1 It is commonly used as a solvent in paint, cosmetic and pharmaceutical industries 2 and as a detergent to remove oil, grease and other treatment dirt from printed circuit boards. 3,4 However, isopropanol is a risk to human health and will slightly irritate the airways at concentrations >400 ppm.…”

Au/ZnO/In2O3 nanoparticles for enhanced isopropanol gas sensing performance

“…Recently, many industrial exhaust gases have been generated with the development of industry, which will continuously contaminate the air and harm human health. 1 Isopropanol (C 3 H 8 O), a typical volatile organic compound (VOC) gas, has attracted attention and has been used in many elds, such as pharmaceuticals, cosmetics, plastics, spices, and coatings. 2,3 In particular, isopropanol is slightly toxic and shows a certain carcinogenicity, so the World Health Organization (WHO) lists it as a category-III carcinogen.…”
