Synthesis and visible-light photocatalytic property of spinel CuAl2O4 for vehicle emissions

A novel CuAl2O4/MoS2/BaFe12O19 magnetic photocatalyst simultaneously coupling type I and Z-scheme heterojunctions for the sunlight-driven removal of tetracycline hydrochloride

“…15–24 Copper aluminate (CuAl 2 O 4 , CAO) is a commonly used photocatalyst because of its high charge transfer and separation efficiency, high thermal and chemical stability, environmental friendliness and other advantages, and it is widely used to degrade dyes, antibiotics and other pollutants that are difficult to degrade naturally. 25–28 Interestingly, the combination of other excellent semiconductor materials with CAO can greatly enhance the electron and hole transfer and separation efficiency of a system, thus enhancing the photocatalytic activity of the system. 29 Molybdenum disulfide (MoS 2 , MS) is considered a lamellar semiconductor material with high photocatalytic activity and a high optical absorption coefficient of visible light and is widely used to degrade dyes, antibiotics and other contaminants.…”
