Summary: The decoration of MnFe2O4 on BiVO4 led to the formation of a Z scheme heterojunction, which prevented charge recombination and produced e(-) and h(+) under visible light. The active oxygen radicals generated effectively degraded tetracycline, and the heterojunction was stable and easily recoverable by an external magnet due to high magnetically activity of MnFe2O4.

Summary: Water is essential for all living things, but industrialization has led to water contamination, affecting ecosystems. The lack of treatment in reusing wastewater is the root issue. Therefore, water treatment is crucial for preserving the ecosystem and human health. In recent years, graphene-based photocatalysts have gained attention for their exceptional properties in wastewater treatment.

Summary: A novel TiO2@ACD@RGO composite photocatalyst was successfully synthesized by a photochemical method, displaying high photocatalytic efficiency for the degradation of BPA with a reaction constant of 0.739 mg/L∙min, attributed to improved electron transfer and mass transfer at the interface. The predominant reactive oxygen species for BPA degradation were identified as O-2(-) and h(+). Additionally, the TiO2@ACD@RGO composite exhibited excellent stability and reusability after five cycles.

Summary: In order to address the presence of fluoroquinolone antibiotics in aquatic environments, it is necessary to design a semiconductor photocatalyst with excellent photocatalytic efficiency. This study explored the performance of MnNb2O6/g-C3N4 composites in the photocatalytic degradation of ciprofloxacin and tetracycline-HCl antibiotics. The enhanced photocatalytic activity of MNO/g-CN was found to be due to the electron's shifting between the MNO and g-CN sheets, promoting the formation of photo-generated e(-)/h(+) pairs, indicating the existence of a low-waste, high-performance material for eradicating ciprofloxacin and tetracycline-HCl from wastewater.
