Traditional degradation methods for N ‐nitrosamines are either confined with acid solution or required for additional chemical reagents to guarantee high reaction efficiency. Herein, we demonstrate a facile and effective way for reagent‐free and pH‐independent degradation of N ‐nitrosamines, which was induced by free electrons generated via corona discharge at ambient pressure. The highly reactive free electron is produced in situ and responsible for degradation of three N ‐nitrosamines, which was also theoretically confirmed. N ‐nitrosamines were believed to be reduced by electrons and to form the radical anion, which underwent a selectively heterolytic cleavage of the N–NO bonds to form the corresponding secondary amines as the degradation products.
