Use of Fe(II)Fe(III)-LDHs prepared by co-precipitation method in a heterogeneous-Fenton process for degradation of Methylene Blue

- Fenton catalyzed by Fe(II)Fe(III)-LDHs were high efficient, with no second pollution.
- Fe(II)Fe(III)-LDHs were of good catalytic activity and high stability.
- Fe(II)Fe(III)-LDHs/Fenton performed well at the range of pH 2-7.
- MB degraded in two pathways simultaneously, following pseudo-second order kinetic.
- New intermediates of MB in Fe(II)Fe(III)-LDHs/Fenton process were detected.
