摘要: CuFe2O4 nanocrystallines with cubic jacobsite structure have been obtained by heat treatment of the coprecipitation product, which were synthesized reaction Cu2+ ions and Fe3+ under alkaline conditions. Reported here is first copper-based catalyst for photocatalytic water oxidation using [Ru(bpy)3]Cl2 as photosensitizer Na2S2O8 sacrificial electron acceptor, respectively. An apparent TOF value 1.2 μmol s−1 m−2 an oxygen yield 72.8% CuFe2O4. The (1.2 m−2) highest among all heterogeneous systems. can be easily separated from solution magnetic separation while maintaining excellent activity in fourth fifth runs. surface conditions are slightly absent after examination X-ray photoelectron spectroscopy (XPS) before reaction.
