摘要

In this study, we report the synthesis of non-metal (N and S)-doped transition metal oxide (TMO) TiO2 (NST) nanocomposites for electrochemical detection and visible-light-driven photocatalysis of the antibiotic drug furazolidone (FRZ). The nanocomposites were synthesized by hydrothermal process and characterized with a wide range of analytical techniques. Electrodes decorated with the nanocomposites (NST) exhibited high sensitivity in detection of FRZ, similar to 16 mu A mu M cm(-1), and a limit of detection of 0.02350 mu M. The sensing platform showed a linear dynamic range of 2 to 100 mu M with a regression value of 0.9992, so it can be used to inspect real samples. The nanocomposites exhibited high photocatalytic activity against FRZ, achieving degradation efficiency of 95 in 140 min. Therefore, the non-metal doped TiO2 nanocomposites have electrochemical and photocatalytic abilities superior to those of typical noble metal-based sensors and photocatalysis.
