Gas Sensors: Diverse Adsorption/Desorption Abilities Originating from the Nanostructural Morphology of VOC Gas Sensing Devices Based on Molybdenum Trioxide Nanorod Arrays (Adv. Mater. Interfaces 14/2016)
Source abstract
Abstract
3D-network of ultra-fine single-crystal α-MoO3 nanorod array based gas sensors show a prompt response and discrimination to volatile organic compounds (VOCs). S. Cong, T. Sugahara, and co-workers illustrate that performance of the sensors strongly depends on the specific morphologies of the nanorod arrays, such as length, number and coverage of nanorods in the 3D network in the article 1600252. The nanorod arrays are spontaneously grown with functionally tunable morphology by a simple single-step solution route. The conductance modulation of the nanorod arrays is attributed to hydrogen ions decomposed from VOCs intercalated into the van de Waals's gaps of layered α-MoO3 and the subsequent reduction of cornered oxygen to H2O.
