摘要: Abstract Cu2(OH)3Cl was synthesized as catalysts for mineralizing aromatic organics via Fenton reactions. Both Cu+ and Cu2+ are present in γ-Cu2(OH)3Cl, α-Cu2(OH)3Cl CuOHCl. Among them, γ-Cu2(OH)3Cl with the highest percentage is most active. Under relatively mild conditions, 88.7 % phenol, more than 85 bisphenol A, benzoic acid, 2-chlorophenol salicylic acid around 79 aniline mineralized at their ambient pH. Compared to reference CuSO4, CuO Cu2O, shows better mineralization ability, HO production H2O2 utilization efficiency. can form σ-Cu-ligand complexes phenolic hydroxyls contaminants. Such readily attacked by H2O2, causing electron transfer from rings formation of . Moreover, self-redox property when induced initiating thus reducing into Cu+. These effects could accelerate regeneration improve
