Alternative title: High-Performance Carbon Nanotube Gas Sensors Using Chemical Reaction Selectors

Description:

The use of single-walled carbon nanotubes (SWCNTs) as transducer elements in gas sensors enables room-temperature operation and low power consumption; however, their overall sensing performance is often limited when based solely on molecular adsorption. This article highlights our recent work on SWCNT-based gas sensors in which chemical reactions are deliberately incorporated into the sensing system to enhance both sensitivity and selectivity. By combining supramolecular chemistry, condensation reactions, catalytic conversion, and mechanical operations, highly sensitive and selective detection of nerve agents, aldehydes, and ethylene has been achieved. These studies demonstrate that incorporating well-defined chemical reactions as selector elements provides a versatile design strategy for next-generation gas sensor systems.
