Microstructural control and selective C_2H_5OH sensing properties of Zn_2SnO_4 nanofibers prepared by electrospinning

摘要

Microstructural evolution of spinel Zn_2SnO_4 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 Zn_2SnO_4 fibers exhibited superior C_2H_5OH sensing response. One dimensional (ID) metal oxide nanostructures, such as wires, tubes, rods and belts, have been explored extensively for potential applications in chemical sensors, catalysts, rechargeable batteries, photonic devices, and transistors. The electrical, optical and catalytic properties of these ID metal oxides are strongly correlated with their shape, size and structures.
