The development of gas sensors with high sensitivity to multiple VOCs is of great significance to protect human health. Herein, we proposed a sensitive ZnO/WO₃ composite chemi-resistive sensor facilely fabricated via a sacrificial template approach. Based on the transferable properties of self-assembled monolayer colloidal crystal (MCC) templates, two-dimensional honeycomb-like ordered porous ZnO/WO₃ sensing matrixes were constructed in situ on commercial ceramic tube substrates with curved and rough surfaces. The nanocomposite thin films are about 250 nm in thickness with large-scale structural consistency and integrity, which Nanomaterials (Basel, Switzerland)Facile Synthesis of ZnO/WO₃ Nanocomposite Porous Films for High-Performance Gas Sensing of Multiple VOCs.PMC996594011974352YJKYYQ2021000952271242YZJJKX2022025200130552201167Zhao QLu YZhang HLei BXiao TKong JWei YLiu WCai WfalseFacile Synthesis of ZnO/WO₃ Nanocomposite Porous Films for High-Performance Gas Sensing of Multiple VOCs.Volatile organic compounds (VOCs) in indoor environments have typical features of multiple components, high concentration, and long duration.
