This paper reviews the fabrication of zinc oxide-tin oxide (ZnO-SnO2) nanocomposite in humidity sensors. ZnO and SnO2 each has a wide energy band gap, making them suitable for producing high-quality humidity sensors. Also, ZnO and SnO2 are the ideal heterojunctions with high sensitivity and thermal stability. When combined, ZnO-SnO2 nanocomposite is an n-type semiconductor with high versatility in many applications, such as gas sensors, lithium-ion batteries, and photocatalytic degradation. Besides, the nanostructure film of ZnO-SnO2 is relatively easy to prepare and characterise while manipulating ZnO and SnO2 could enhance device performances. Thus, the nanostructure of ZnO-SnO2 would likely measure the humidity sensing performance easily. © 2023, Universiti Malaysia Perlis. All rights reserved.
