A novel LaFeO3 catalyst synthesized from sodium diethylenetriamine pentamethylene phosphonate for degradation of diclofenac through peroxymonosulfate activation: degradation pathways and mechanism study

A series of LaFeO 3 catalysts were prepared using the sol–gel method with sodium diethylenetriamine pentamethylene phosphonate as the complexing agent and were applied to activate PMS to produce active oxides to degrade DCF.
