Recently, ternary nanocomposites have received attention due to their inimitable properties and various applications. In this paper, the Magnesium Oxide/Silver Oxide/Zinc oxide (MgO/Ag2O/ZnO) nanocomposite was prepared via a green process with Mentha pulgium plant extract. The phytochemicals present in plant extract can facilitate the reduction of metal ions, forming nanocomposites. The sample was investigated by the application of FT-IR, UV-Vis, XRD, FESEM/EDS, and Mapping analyses. The XRD spectrum displayed the crystallite structure of nanocomposite with an average crystallite size of about 43.9 (500 °C) and 39 nm (600 °C). FESEM/PSA analysis showed spherical and hexagonal morphology with an average size of about 33.8 nm. Also, EDS analyzes the confirmed existence of zinc, Magnesium, Silver, and Oxygen elements. The outcomes of photocatalytic activity depicted that the degradation percentage of MB (methylene blue) dye (pH = 9.5, dose of synthesis sample ∼ 30 mg, concentration of dye ∼ 0.5 × 10− 3 M, and light source: UVA) was about 98% after 120 min. Also, the toxicity of the nanocomposite was estimated against cancer PC12 and normal L929 cell lines through the MTT test. The results showed that no significant toxicity was observed against normal cells, but cancer cells reported an IC50 value of about 123.7 µg/mL.
