Synthesis of boron nitride doped polypyrrole hybrid nanocomposites for photocatalytic degradation of 2-chlorophenol from aqueous solution / Faizah Mohammad Yunus

This investigation was focusing on the photocatalytic degradation of toxic compound in waste water by using nanocomposite. In this study, boron nitride was doped with conducting polypyrrole via oxidation in-situ polymerization method using FeCl3 as oxidation agent to form nanocomposite. The synthesized h-BN/PPy nanocomposites were comprehensively characterized using X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). The photodegradation of 2-chlorophenol was performed under direct sunlight for 3 hours and using different parameter such as different pH, contact time and initial concentration. The optimum results were achieved in concentration of 50 mg/L, at pH 6, and 3 hours of contact time. This optimized experiment condition yield a 91.07% degradation of 2-chlorophenol by BN/PPy nanocomposite. The results indicated that BN/PPy nanocomposite was the most efficient in photocatalytic activity compared to pure polypyrrole and pure boron nitride
