Smart formaldehyde detection enabled by metal organic framework-derived doped electrospun hollow nanofibers

In this work, the metal-organic framework (MOF)-derived Zn2+ doped SnO2 (ZZS) hollow nanofibers (HNFs) have been successfully synthesized via facile electrospinning and annealing techniques for achieving the low concentration of HCHO monitoring. As the hollow nanostructure and the optimized Zn2+ homogeneous doping behavior ensure all the smooth electrons transfer, abundant chemisorbed active sites and oxygen vacancies, the 15 wt% ZZS HNFs...
