AbstractBimetallic iron and copper oxide nanoparticles (NPs) supported on hydroxylated diamond (D3) exhibits an improved activity for the heterogeneous Fenton phenol degradation under natural or simulated sunlight irradiation with respect to analogous monometallic samples or than analogous FeCu NPs on graphite, activated carbon and P25 TiO semiconductor. FeCu/D3 catalyst exhibits good recyclability and stability especially working at pH 6. Overall, the high activity of the FeCu(0.2 wt%)/D3 catalyst is mainly due to the combination of the high activity of reduced copper species decomposing HO to HO radical, while Fe allows the regeneration of these reduced copper species.
