Nitrite is widely used as a food additive, and it is of great significance to realize accurate detection of nitrite for food safety. Electrochemical technique is characterized by simple operation and portability, which enables rapid and accurate detection. The key factors affecting the nitrite detection performance are the electrocatalytic activity and interfacial electron transfer efficiency of the electrode. The electrochemical oxidation of nitrite typically requires high potentials, posing challenges for detection. Therefore, we need to develop a high-performance sensitive electrode to fulfill the need for efficient detection of nitrite. (89)
