Highly ordered mesoporous Fe3O4@carbon embedded composite was prepared and grafted onto monolithic carbon aerogel to form a composite cathode (Fe3O4@OMC/CA). The Fe3O4@OMC/CA was used as heterogeneous electro-Fenton cathode for the degradation of dimethyl phthalate (DMP). 95% removal and 65% mineralization of DMP was achieved within 120min. Highly dispersed Fe3O4 nanoparticles increased the number of catalytic active sites, and the OMC layer provided accessible pathway to the catalytic active sites and reduced the resistance of mass transport. The main oxidants were OH and the surface-controlled heterogeneous catalysis was the critical step. The composite cathode remained electrocatalytic activity after five consecutive runs.
