Herein, wereportthesuccessfulfabricationofhighlysensitive,reproducibleandreliablenitroaniline
chemical sensorbasedonZnOdopedCeO2 nanoparticles. TheZnOdopedCeO2 nanoparticles were
synthesized throughasimple,facileandrapidmicrowave-assistedmethodandcharacterizedbyseveral
techniques.Thedetailedcharacterizationsconfirmed thatthesynthesizednanoparticlesweremono-
disperse andgrowninhighdensityandpossessinggoodcrystallinity.Further,thesynthesizedZnO
doped CeO2 nanoparticles wereusedasefficient electronmediatorsforthefabricationofhighsensitive
nitroaniline chemicalsensors.Thefabricatednitroanilinechemicalsensorexhibitedveryhighsensitivity
of 550.42 μAmM1 cm2 and experimentaldetectionlimitof0.25mM.Tothebestofourknowledge,
this isthe first reportinwhichCeO2–ZnO nanoparticleswereusedasefficient electronmediatorsforthe
fabrication ofnitroanilinechemicalsensors.Thus,presentedworkdemonstratesthatZnOdopedCeO2
nanoparticles arepotentialmaterialtofabricatehighlyefficient andreliablechemicalsensors.
