摘　　要：For the first time, an efficient, green, economical biomimetic catalyst （hemin-cetyltrimethylammonium bromide micelles） was discovered to degrade 2,4,6-trichlorophenol （TCP）. The degradation experiments indicate that pH, temperature, the addition of 2-methyIimidazole, and the amount of hydrogen peroxide influence the degradation process. Test of reusability revealed that CTAB micelles can protect hemin from destruction by H202 and that the materials can be recycled. This material can be of great use for waste-water treatment.For the first time, an efficient, green, economical biomimetic catalyst(hemin-cetyltrimethylammonium bromide micelles) was discovered to degrade 2,4,6-trichlorophenol(TCP).
