Descrição: dc.descriptionVolatile organic compounds (VOCs) can be associated with some diseases when found in human exhaled breath as a result of alterations in metabolic pathways. Therefore, the development of highly selective sensors to a particular VOC is required. In this paper, we used silica (SiO2) nanospheres as support for the growth of cobalt (II) oxide (CoO) nanosheets, resulting in the SiO2@CoO core-shell structure with a high specific surface area. This structure was applied as a chemoresistive VOCs sensor. The SiO2@CoO material exhibited increased sensitivity to 2-butanone in comparison with acetone, methanol, ethanol, isopropanol, acetaldehyde, benzene, toluene, and m-xylene. The response to 100 ppm of 2-butanone was ~44.7, with a response time of 27 s. The enhanced performance might be attributed to the high surface area provided by the unique core-shell structure with 2D CoO nanosheets.-
