Enhancing Formaldehyde Selectivity of SnO<sub>2</sub> Gas Sensors with the ZSM-5 Modified Layers
High performance formaldehyde gas sensors are widely needed for indoor air quality monitoring. A modified layer of zeolite on the surface of metal oxide semiconductors results in selectivity improvement to formaldehyde as gas sensors. However, there is insufficient knowledge on how the thickness of...
