Catalytic activity of LaCu0.5Mn0.5O3 perovskite at circumneutral/basic pH conditions in electro-Fenton processes

A great challenge in electro-Fenton processes is the development of active heterogeneous catalysts at circumneutral or even basic pH order to avoid acidification wastewater effluents and generation an undesirable metallic sludge after treatment. In this work, LaCu0.5Mn0.5O3 perovskite has been assessed as catalyst for removal methylene blue dye model pollutant. The tested a wide range pH, from acidic (3) (8.5) values. effect loading, applied voltage air flow was also studied on efficiency process. showed remarkable activity low current density 2.6–0.9 mA/cm2. durability five successive runs. XRD patterns reused evidenced high stability structure several copper leaching aqueous phase (< 0.05 mg/L Cu) proves material its main contribution overall system.
