Abstract

The simple reflux method was employed to grow the unique lotus-leaf (LL) like ZnO nanostructures on the FTO substrate and utilized as working electrode for the fabrication of ethyl acetate (EA) chemical sensor at low level detection. Well-defined and uniform lotus-leaf like morphology was observed which possessed the average size of ~100-150 nm. The synthesized LL-ZnO nanostructures were highly crystalline, pure and exhibited typical wurtzite hexagonal structure. The fabricated EA chemical sensor based on LL-ZnO electrode displayed substantially high sensitivity of ∼139.8 μA mM^-1 cm^-2, the limit of detection (LOD) of ∼0.26 mM, with correlation coefficient (R) of ∼0.9749.
