Abstrakt: Modifiable one-dimensional materials are extremely desired in various applications, especially in room-temperature (RT) chemiresistive gas sensing. New one-dimensional (1D) CdS-based metal chalcogenide nanowires with a surface fully covered amino group (denoted as Cd-ATP) were prepared by the coordination self-assembly method. Featuring densely covered organic functional motifs, Cd-ATP is able to selectively recognize H2S through hydrogen bonding interaction between the amino group and H2S. Cd-ATP exhibits high sensitivity, an ultra-low limit-of-detection (116.49 ppt) and fast response/recovery among all reported room temperature H2S sensing non-composite materials. This work provides inspiration for the design and preparation of novel surface fully functionalized 1D materials for various chemical applications. [ABSTRACT FROM AUTHOR]
