Biosynthesis of MgO nanoparticles using Annona squamosa seeds and its catalytic activity and antibacterial screening

Abstract

Biologically and catalytically important magnesium oxide nanoparticles (MgONPs) have been synthesised successfully in an eco-friendly mode using Annona squamosa seeds. The synthesised nanoparticles were characterised by spectroscopic analysis methods. UV–vis, XRD powder diffraction and EDX were used to confirm the nanoparticles’ stability, phase identification and element content, respectively. SEM and TEM were also used to predict the size and morphology of the nanoparticles. The biogenic synthesis of MgONP has been judged for its antibacterial activity against Pactobacterium carotovorum and for its catalytic activity in the synthesis of 2-benzimidazole and has been shown to be potentially effective against pathogenic strain and in terms of catalytic activity in the formation of benzimidazole.
