Gas Sensors
In article number 2105869, Jihan Kim, Il‐Doo Kim, and co‐workers present a multifunctional chemiresistive gas sensor composed of nanofiber yarn sputter deposited with an oxide sensing layer, and then coated with ZIF‐8 for nanofiltration of gas analytes. Through comprehensive sensing experiments and molecular modeling, they demonstrate that this concept of introducing bistacked oxide/molecular...
Though highly promising as powerful gas sensors, oxide semiconductor chemiresistors have low surface reactivity, which limits their selectivity, sensitivity, and reaction kinetics, particularly at room temperature (RT) operation. It is proposed that a hybrid design involving the nanostructuring of oxides and passivation with selective gas filtration layers can potentially overcome the issues with...
