英文摘要	Background: Based on the advanced oxidation process of transition metal activated peroxymonosulfate (PMS), a heterogeneous catalyst with simple synthesis strategy and high efficiency was prepared. It was used to remove refractory organic pollutants. Methods: We designed a biochar modified cobalt-iron bimetallic composite catalyst (BC@CFC) via co-precipitation and calcination methods using biomass and cobalt-iron layered double hydroxide as precursors. Significant Findings: BC1@CF2C exhibited a unique multi-level porous layered structure, which reasonably reduced the agglomeration of cobalt-iron composite and increased the specific surface area. This allowed the catalyst to create more exposed active sites and favorably activate PMS, with a rapid and efficient degradation of tetracycline (TC) in 5 min (92.49%±0.21%) and 30 min (96.63%±1.68%). BC1@CF2C was magnetic and easy to recover, it maintained a superior TC removal rate (about 90%) after 5 cycles. This remarkable performance was benefited from the synergistic effect of cobalt-iron bimetal to enhance the activation effect of PMS, which led to the production of sulfate free radicals (SO4•−) and hydroxyl free radicals (•OH) to further attack TC. BC@CFC possessed the advantages of being environment-friendly, high catalytic activity and sustainability, which could be of great value in environmental application. © 2022 Taiwan Institute of Chemical Engineers
