In this study, BiVO 4 synthesized by hydrothermal and calcination methods were explored as catalysts in the ammoxidation of dichlorotoluenes to shed light on the structure‐reactivity correlations. The BiVO 4 samples were characterized by X‐ray diffraction (XRD), temperature‐programmed reduction (TPR), Brunauer–Emmett–Teller (BET), and UV–Vis spectrophotometry. The results showed that the catalytic activity of BiVO 4 greatly relied on the structure variations. The hydrothermal prepared BiVO 4 exhibited better catalytic activities as a consequence of its greater structure deformation, with maximum yields of 73.1, 72.2, and 70.8% for 3,4‐, 2,4‐ and 2,6‐ dichlorobenzonitrles, respectively.
