Abstract:
Manganese oxide (MnO) nanoparticles are essential materials in various applications such as sensors, catalysis, molecular adsorption, electronics, and exhibited excellent antimicrobial activity. Due to the numerous demerits of current nanoparticle synthetic approaches, there is a surge in the exploration of efficient methods for the synthesis. This study involved the synthesis of MnO nanoparticles through a simple, cost-effective, and time-efficient co-precipitation method by using manganous sulphate (۰.۰۳ M) and sodium hydroxide (۰.۰۰۹ M). The UV-Vis absorption showed sharp absorption at ۳۲۰ nm confirming the presence of MnO nanoparticles. The FTIR spectral analysis depicted absorption bands at ۴۸۰ cm-۱ and ۵۱۵ cm-۱ correspond to the characteristic peak of the Mn-O bond and XRD spectra predicted the average size of synthesized nanoparticles to be ۱۱ nm. The elemental composition of the nanoparticles was determined by EDX analysis. The synthesized nanoparticles showed significant antimicrobial activity against microorganisms, Staphylococcus aureus, Klebsiella pnuemoniae, and Candida albicans.
