High-performance electrochemical nitrite sensing enabled by the commercial carbon fiber cloth

Abstract

Carbon fiber cloth (CC), by virtue of its flexible, conductive, and low-cost features, has prompted great interest as the underlying backbone in many electrochemical reactions. Here, we report on our recent finding that the CC could be directly employed as an anode for nitrite detection. It possessed surprisingly high sensing performance toward nitrite with low determination and detection limit, high sensitivity, wide linear detection range, excellent selectivity and stability, as well as good feasibility of testing nitrite in actual samples. Note that these parameters of CC are comparable or even superior to those for most of reported carbon-, transition metal-, and noble metal-based advanced nitrite sensors. We also proved that the acid-oxidized CC with rougher surface and more carbon-oxygen functional groups exhibited higher current response and sensitivity toward the nitrite. The advantages including superior sensing performance, low electrode cost, no additional synthetic or complex pretreatment processes involved, and commercial off-the-shelf nature enable the CC to be an ideal electrochemical sensor for nitrite determination.
