Abstract

A Co₂(OH)₃Cl catalyst was prepared by deep eutectic solvent and applied to decompose p-nitrophenol (4-NP) by O₃. Within 30 min, the removal efficiency of Co₂(OH)₃Cl catalyst for 4-NP reached 92.9%, which is much higher than that of Co(OH)₂ or Co₃O₄ catalyst. In a wide pH range (3–11), the catalyst showed good catalytic performance for 4-NP removal. The production of highly active free radicals such as ¹O₂ and O₂[rad]⁻ is conducive to efficient degradation. Furthermore, the catalyst showed good stability and recoverability.
