제목 Ethylenediamine organic chemical detection by field-effect transistor sensors fabricated with Bismuth-Vanadium Oxide-Tungsten Oxide (Bi(V2O4)-WO2) nanosheets
초록 This work reports the preparation of bismuth-vanadium oxide-tungsten oxide Bi(V2O4)-WO2 nanosheets (NSs) via hydrothermal method at low temperature and utilized as the electrochemical electrode for fabricating field-effect transistor (FETs) based sensor. Synthesized Bi(V2O4)-WO2 displayed defined and thin sheet like morphology with the average thickness of ~35 nm. The synthesized Bi(V2O4)-WO2 NSs fabricated FET sensor was benefited by the large surface area, resulted in the fast detection of ethylenediamine chemical at very low concentration. The sensing results displayed a reproducible sensitivity of ~13.27 mAmM−1cm−2, detection limit of ~72.15 nM with the correlation coefficient (R) of ~0.99644 and good linearity from 10 mM to 100 mM. The fabricated Bi(V2O4)-WO2 NSs FETs sensor exhibited reproducibile and excellent stability of sensing performance and thus, confirmed it as useful tool for water maintaining system.
