Nanomaterials, as an active ingredient, have been widely deployed in various science and technological applications with zinc and titanium oxides nanoparticles being commonly applied in sunscreens. On similar lines, cerium oxide nanoparticles (CeO 2 -NPs) were synthesized using Musa sapientum peel extract, to investigate its cytotoxic effects, UV protection and photocatalytic activity. The synthesized nanoparticles were identified through Raman, Powder X-ray Diffraction (PXRD), Fourier-Transform Infrared spectroscopy (FT-IR), Transmission Electron Microscopy (TEM), Field Emission Scanning Electron Microscopy (FESEM) and Energy-Dispersive Spectroscopy (EDX). FESEM results showed that the size of synthesized nanoparticles is in the range 4–13 nm. Their cytotoxic activity revealed a non-toxic behavior in concentrations below 500 μg/mL on lung (A549) cell lines. The Sun protection factor (SPF) was estimated approximately ~ 40 for synthesized CeO 2 -NPs. The survey of photocatalytic activity showed that synthesized nanoparticles can remove 81.7% of AO7 in 180 min under visible light.
