Sustainable Synthesis of MgO Nanoparticles from Clerodendrum inerme Bast Fiber Extract: Physicochemical Characterization and Antibacterial Performance
Abstract
The need of sustainable and biocompatible nanomaterials has been driving environmentally friendly synthesis pathways related to biomedical purposes. In this research, magnesium oxide (MgO) nanoparticles were produced through a green technique using Clerodendrum inerme bast fiber extract as a plant-based reducing and stabilizing agent. X-ray diffraction showed the presence of crystalline MgO with typical peaks of 24.7°, 33.8° and 38.4° which indicates that it has a face-centered cubic structure and the crystallite size is between 22 and 34nm in size on average. Fourier-transform infrared spectroscopy showed the presence of significant functional groups with peaks at 3307, 2885, 1574, 953, and 450cm-1, which are related to phytochemical capping and the formation of Mg-O lattices. The SEM analysis revealed abnormal, porous nanostructures with particle sizes of less than 50nm and agglomerated clusters of 100-500nm. Elemental analysis using energy-dispersive X-ray analysis revealed the presence of Mg (56.4wt%), O (39.72wt%), and C (3.44wt%). Multi-stage thermal degradations with initial weight loss of 6-8% (0-100℃) and 12 -15%, and extensive decomposition of 40-55% were observed by thermogravimetric analysis. The structural integrity was preserved up to approximately 230℃ with a residual mass of 22-25% at 600℃. The synthesized MgO nanoparticles were found to have an excellent antibacterial effect on Pseudomonas aeruginosa with inhibition zones of 36.5 ± 1.2 mm (100 µg) and 32.8 ± 1.0mm (50 µg). The standard erythromycin exhibited an inhibition zone of 35.0 ±0.9mm.
