Abstract：
In this article, catalytic degradation of chlorinated organic compounds by nano-Co3O4 was studied by gas chromatography and GC-MS using 1,2,4trichlorobenzene as the model compound. The results showed: nano-Co3O4 showed high activity for catalytic degradation of 1,2,4-trichlorobenzene, when 200 mg of nano-Co3O4 reacted with 1.5 μL 1,2,4-trichlorobenzene at 300 ℃ for 60 min, the degradation efficiency was nearly 100%. Hydrodechlorination may occur dominantly, and during the hydrodechlorination process, the main path was successive dechlorination of 1,2,4-TrCB to form p-dichlorobenzene (p-DCB) and then p-DCB to form monochlorobenzene.
