Photocatalytic degradation of polypropylene film using TiO2-based nanomaterials under solar irradiation

An efficient and enhanced photocatalytic degradation of polypropylene film was studied by utilizing TiO2-rGO nanocomposite under solar irradiation for 130 h. Characterization tools such as XRD, FT-IR, FE-SEM and ToF-SIMS ensure the photodegradation. Higher value of carbonyl index and formation of cavities (diameter; ~ 500 nm) were noted via FT-IR and FE-SEM, respectively.209
