Abstract
- Yolk-shell SnO2 mesoporous double-layer nanotubes were synthesized in one-step by single nozzle electrospinning. Compared with the traditional electrospinning using polyvinylpyrrolidone (PVP) as the precursor polymer to obtain the single nanotube material, two PVPs (PVPK88-96 and PVPK23-27) with different molecular weights in solution coupled with Sn2+ easily form the core-shell structure nanofiber through phase separation. The yolk-shell double-layer SnO2 nanotubes were obtained after calcination at 600 °C for 2 h. The yolk-shell SnO2 mesoporous double-layer nanotube is a promising sensing material toward 3-hydroxy-2-butanone as it shows high sensitivity, cycling stability, and selectivity. Moreover, the response and recovery times of the yolk-shell SnO2 mesoporous double-layer nanotubes toward 1 ppm 3-hydroxy-2-butanone were 122 s and 117 s. [ABSTRACT FROM AUTHOR]
