In situ growth of α-Fe₂O₃ nanorod arrays on 3D carbon foam as an efficient binder-free electrode for highly sensitive and specific determination of nitrite

Abstract

3D α-Fe₂O₃ nanorod arrays (NAs)/carbon foam (CF) architectures have been successfully fabricated as binder-free electrodes for the determination of nitrite, exhibiting high sensitivity and excellent specific recognition as well as feasibility in real water samples.
