Structural and biological properties with enhanced photocatalytic behaviour of CdO-MgO nanocomposite by microwave-assisted method.

CdO-MgO nanocomposite was synthesized and investigated using various spectroscopic techniques. The cubic structure of CdO-MgO nanocomposite with an average crystallite size 35 nm was confirmed through XRD. FTIR infers the characteristic vibrational frequencies as CdO-MgO (455, 527 cm−1). The optical bandgap of the prepared nanocomposite is 5.39 eV via the UV–vis spectrum. The photocatalytic degradation efficiency of CdO-MgO nanocomposite was analyzed under direct sunlight irradiation against the (Methylene blue: 90 % at 90 min & Congo red: 90 % at 120 min) dyes. The antimicrobial activity of prepared nanocomposite was scrutinized against foodborne pathogens. Anti-breast and lung cancer activity (IC 50) of the synthesized nanocomposite was examined against the MCF-7 and A 549 cancer cell lines. [ABSTRACT FROM AUTHOR]
