LaFeO3 Perovskite as New and Performant Catalyst for the Wet Peroxide Oxidation of Organic Pollutants in Ambient Conditions

The purpose of the present study was to evaluate the ability of LaFeO3 perovskites prepared using the self-combustion method to behave as efficient and stable catalysts in phenol oxidation using H2O2 in ambient conditions. Depending on the synthesis conditions, strong differences in the structural, textural and reducibility characteristics of the perovskites, as well as in phenol conversion and TOC abatement level were observed. High TOC abatement (76%) and very low iron leaching (0.27 wt%) were obtained at 40 A degrees C in the presence of LaFeO3 nanoparticles exhibiting the lowest crystal domain size.
