Regenerable magnetic octahedral layer catalyst for gaseous UPOPs removal

- Magnetic manganese oxide layer catalysts (Fe/OL and Fe/Cu-OL) were synthesized by facile method.
- The catalytic performance of Fe/OL and Fe/Cu-OL on the removal of gaseous persistent organic pollutants was investigated.
- Long-term reaction was conducted and spent catalysts could be regenerated by simple water-washing method.
- The important roles of tunnel K+ in reaction, deactivation and regeneration process were highlighted.
