CeO2/ZIF-9 composites as a heterogeneous catalyst for peroxymonosulfate activation to degrade methylene blue
In the present work, a novel CeO 2 /ZIF-9 composites were prepared, characterized and used as a multiphase catalyst to activate peroxymonosulfate (PMS) to degrade methylene blue (MB). The effects of Ce/Co molar ratio, catalyst dose, PMS concentration, initial solution pH and reaction temperature wer...

/ZIF-9 composites were prepared, characterized and used as a multiphase catalyst to activate peroxymonosulfate (PMS) to degrade methylene blue (MB). The effects of Ce/Co molar ratio, catalyst dose, PMS concentration, initial solution pH and reaction temperature were explored. The results showed that 20 mg/L MB was almost absolutely degraded, and the removal rate of COD reached 77.8% by 150 mg/L PMS activated with 50 mg/L 0.50-CeO
