Abstract
The aligned zinc oxide (ZnO) nanotubes (NTs) thin film was grown on fluorine doped tin oxide (FTO) substrates by low temperature solution method and utilized as a smart working electrode for the fabrication of ethanolamine chemical sensor. The synthesized ZnO possessed well crystalline tubular morphology with typical hexagonal wurtzite phase. The aligned ZnO NTs thin film presented a good optical band gap of â¼3.31 eV which was nearly close to the bulk ZnO nanomaterials. The fabricated ethanolamine chemical sensor based on aligned ZnO NTs thin film electrode showed significantly high sensitivity of â¼37.4Ã10â4 mA mMâ1 cmâ2, good linearity of â¼0.05 mM-1 mM and the detection limit of â¼19.5 µM with correlation coefficient (R) of â¼0.9850.
