Owning to both well‐defined active sites and high site densities, Co‐MOFs have emerged as a promising catalyst for their performance. Herein, Co(CN) 3 with cubic structure morphology are successfully synthesized via hydrothermal method. As the activator of peroxymonosulfate (PMS), is applied degradation tetracycline hydrochloride (TC) first time. At optimized reaction conditions ([catalyst] = 0.1 g · L −1 , [TC] 20 mg [PMS] mmol·L initial pH 7, T 25 °C), efficiency achieves 94%. Coexisting dissolved organic matter Cl − ions reduce TC by noticeable percentage, while HCO H 2 PO 4 slightly prevent process. Mechanism investigations suggest that SO •− 1 O play crucial roles in catalytic Recycling experiments demonstrated performance remains at 55% after four cycles. This work offers novel insights into activating PMS.
