ABSTRACT
The electrochemical sensing is a potential method for detection of trace toxic substance. Herein, the heterojunction of netlike ZnO/BiOCl nanosheets was constructed for the enhanced electrochemical detection of ammonia. Cyclic voltammetry and linear sweep voltammetry were used to investigate the electrochemical performance. The results show that the ZnO/BiOCl-modified electrode exhibits higher sensitivity towards ammonia compared with the ZnO and BiOCl-based electrodes, which is ascribed to band structure and fast electron transfer. The high response of 11.8â
µA mM-1 and a low detection limit (LOD) of 0.25â
µM are achieved. In addition, the ZnO/BiOCl material exhibits high selectivity, repeatability and stability. The better linear relationship between concentration and current (R2 =0.99) is significant for quantitative detection of ammonia, implying that netlike ZnO/BiOCl nanosheets can serve as electrochemical sensing platform for detecting toxic substance. This research provides a strategy for fabricating two-dimensional netlike materials and regulating heterojunctions used for electrochemical application.
