Microstructural control and selective C2H5OH sensing properties of Zn2SnO4 nanofibers prepared by electrospinning.

Microstructural evolution of spinel Zn2SnO4 nanofibers was manipulated via an in situ phase separation process of inorganic precursors and a matrix polymer during electrospinning and calcination. Chemiresistive gas sensors using porous Zn2SnO4 fibers exhibited superior C2H5OH sensing response.
