Enhanced ethanol sensing properties of NiO@ZnO core-shell nanofibers with P-N heterojunction

Abstract

Herein we have fabricated NiO@ZnO core-shell nanofibers (CSNFs) via a facile two-step method. Nickel nitrate/polyacrylonitrile (Ni(NO3)2/PAN) composite nanofibers were synthesized firstly by electrospinning, and atomic layer deposition (ALD) technique was applied to control the deposition of ZnO shell layers. After annealing at 600 °C in air, well-defined… (More)
