Bio-synthesis of lead oxide nanoparticles using Chinese Mahogany plant extract (CMPE@LO) for photocatalytic and antimicrobial activities

Abstract

Abstract The current study describes the plant-mediated synthesis of lead oxide nanoparticles using a plant extract from Chinese Mahogany. The prepared nanoparticles were characterized using techniques like Fourier transform infrared spectrogram (FTIR), X-ray diffractometer (XRD), field emission scanning electron microscope (FESEM), high resolution transmission electron microscope (HRTEM) and thermo-gravimetric analysis (TGA). XRD results confirmed the crystalline nature of the nanoparticles. The Chinese Mahogany plant extract-lead oxide (CMPE@LO) nanoparticles were used to evaluate photocatalytic behavior against fast green (FG). It was observed that 90.22 % of fast green (FG) has been removed within 3 hours. The various operating parameters such as effect of time, concentration of fast green and photo catalyst amount were also studied and optimized for maximum removal. The kinetic study was investigated using pseudo-first model having good value of regression coefficient (R2). The antibacterial properties of the prepared nanoparticle against several bacteria including B. subtilis, S. aureus, and E. coli, were also investigated. The synthesized CMPE@LO nanoparticles shows higher zone of inhibition as compared to inorganic or organic moiety.
