Functional Nanomaterials

Part of the book series: Materials Horizons: From Nature to Nanomaterials ((MHFNN))

Abstract

UV-enhanced gas sensors using functional nanomaterials have been studied widely, aiming to lower the operating temperature and thus lower the power consumption. This chapter demonstrates UV-enhanced oxide nanostructures and their working principle, issues, and gas sensing performance. Mainly, current states on zinc oxide and their hybrid nanocomposites with other metal oxide and 2D materials, their fabrication methods, and sensing properties have been discussed. Moreover, it also demonstrates the strategies to achieve gas sensing performance under controlled conditions. Finally, summary and some aspects for the future outlook have been discussed on light-activated functional nanomaterials for next-generation gas sensor devices.
