Popis: In this paper, MgO and CuO/MgO nanomaterials were green-synthesized by Opuntia monacantha plant extract. Phytochemical analysis of methanolic extract of the plant showed the presence of terpenoids and flavonoids which are responsible for the synthesis of nanoparticles. XRD revealed the crystalline nature of cubical MgO and CuO/MgO nanocomposite that exhibited additional peaks related to CuO nanomaterial. FESEM images confirmed 2D flower-like nanosheets of MgO and defective crumpled structure of CuO/MgO nanocomposites. CuO adsorbed on interfaces of MgO nanosheets by making Cu–O–Mg linkage is studied in FTIR spectrum. Improved optical features of CuO/MgO composite and reduced bandgap were confirmed in UV–Vis analysis. Prepared samples were employed in antimicrobial and photocatalysis applications. The prepared MgO, CuO/MgO nanocomposite and their synergism with standard antibiotics showed significant antimicrobial activity against Candida albicans and Bacillus subtilis. CuO/MgO composite showed a higher degradation of methyl orange (MO) (88%) than MgO. These results are expected to develop a new eco-friendly and cheap MgO and CuO/MgO nanocomposite with potent antimicrobial and photocatalytic applications.
