摘要	In this work, we introduce our recent finding that the carbon fiber paper (CFP) treated by simple air annealing (OCFP) could be used for exceptionally high-performance electrochemical nitrite sensing. The air-annealing process endows the pristine CFP with higher defective edge/plane sites, more oxygen-containing functional groups, higher roughness, and improved wettability. The electrochemical studies show that the OCFP exhibits excellent sensing performance for nitrite, with an ultralow determination limit of 0.1 mu M and a detection limit of 0.07 mu M, an ultrawide linear determination range of 0.1-3838.5 mu M, a fast current response of 1 s, and a high sensitivity of 930.4 mu A mM(-1) cm(-2). These performance values are comparable or even superior to those for most reported noble- or transition-metal-based advanced Besides, this electrode also presents satisfactory stability, reproducibility, and feasibility of nitrite sensing in food ideal monolithic and metal-free catalyst with ultrahigh and stable detection performance, the OCFP has a high integrated into next-generation electrochemical sensing devices.
