2, 4, 6-Trinitrotoluene (TNT) is a frequently used explosive compound, and it easily gathers in soil and water during transportation, use, and storage. Except for the security issue, it also has high toxicity and mutagenic effect on the environment and all life forms. Thus, it is critical to develop high-efficiency sensing methods for the detection of TNT at trace levels with high sensitivity and selectivity. This brief review highlights the research progress of using electrochemical sensors to analyze TNT molecules in recent years. Specifically, this minireview mainly focuses on the recently developed nanostructured electrocatalysts and electrochemical methods combined with other techniques for electrochemical detection of TNT.
