Effect of heat treatment on surface structure and gas sensing of electrospun ZnO‐SnO₂ composite nanofibers

Abstract

ZnO-SnO 2 composite nanofibers with a constant Zn/Sn ratio of 0.4 have been electrospun and calcined at 650°C in ambient air, followed then by heat treatment at 350°C in either air, 5% H 2 -95% N 2 , or 15 ppm H 2 S-air atmosphere for comparison of gas-sensing behaviors. The nanofibers being heat-treated in the H 2 S-air atmosphere How to cite this article: Wu FY, Tseng WJ.
