In-situ functionalized biomass derived graphite-supported BiFeO3 for eradication of pollutants

A novel, green, versatile and magnetically retrievable BiFeO3/CDR (Bismuth ferrite/ coriander) nanocomposites were fabricated via simple wet chemical method utilizing in situ functionalized, cheap coriander seed powder (CDR 5%, 10%, 15% and 20 wt%) as a fuel to enhance the efficiency of pristine BiFeO3. A comparative study was performed between BiFeO3/CDR and BiFeO3/CNT (Bismuth ferrite/carbon nanotubes) nanocomposites for the removal of various hazardous pollutants from waste water. The successful synthesis of the fabricated nanomaterials was monitored via FT-IR, Powder XRD, FE-SEM, CV, VSM, CHNS/O and XPS studies. The synthesized nanomaterials were employed for the oxidative degradation of Carbol fuchsin, Reactive black 5, Ciprofloxacin and Doxorubicin; adsorption of a pesticide malathion; and reduction studies for Para-nitrophenol (PNP). The fabricated nanomaterials (BiFeO3/CDR) showcased excellent efficiency and comparable results with (BiFeO3/CNT) for the removal of model pollutants. Moreover, synthesized green heterojunction was also testified for mixture of textile and pharmaceutical waste. Hence CDR can be utilized as a better alternative of CNTs.
