A novel magnetically separable BiVO4/N-rGO/CuFe2O4 hybrid photocatalyst for efficient detoxification of p-bromophenol

The present work deals with simple hydrothermal preparation of magnetically separable BiVO4/N-rGO/CuFe2O4 Z-scheme hybrid photocatalyst for efficient detoxification p-bromophenol (p-BP). BiVO4 is one the most visible light catalyst, however, suffers photo-corrosion and high recombination charge carriers that restricts its applications. Addition graphene oxide doped nitrogen are believed to overcome these issues. Further addition CuFe2O4 enhances catalytic degradation helps in separating catalyst. With merits could be a promising p-BP. After 60 min irradiation 94.1 ± 1.2% was achieved by (k = 0.01749 min−1) while only 53.8 2.3% observed 0.00674 min−1). catalyst able recover using external magnet showed 86.4% efficiency even after five recycles, which suggested good stability. products identification pathway were proposed based on LC-ESI/MS analysis. Moreover, phytotoxicity assessment investigated Phaseolus vulgaris germination index (GI) about 11.4% pure p-BP, it 83.03% products. Thus, results more p-BP during this photodegradation.
