Summary: | Singlet oxygen (
O
) is a reactive species for the selective degradation of stubborn organic pollutants. Given its resistance to harsh water environment, the effective and exclusive generation of
O
is acknowledged as a key strategy to mitigate water production costs and ensure water supply safety. Herein, we synthesized MnO
intercalated MnFe layered double hydroxides (MF-MnO
) to selectively produce
O
through the activation of PMS. The distinctive confined structure endowed MF-MnO
with a special pathway for the PMS activation. The direct oxidation of BPA on the intercalated MnO
induced the charge imbalance in the MnFe-LDH layer, resulting in the selective generation of
O
. Moreover, acceptable activity deterioration of MF-MnO
was observed in a 10 h continuous degradation test in actual water, substantiating the application potential of MF-MnO
. This work presents a novel catalyst for the selective production of
O
, and evaluates its prospects in the remediation of micro-polluted water. |
