▎ 摘　　要

The pollution caused by oil and its toxic derivatives presents a considerable risk to the public health and the environment. This work is devoted to the study of the influence of TiO2 nanoparticles immobilized on three types of textiles materials (Cotton, Entretela, and Polylactic Acid-PLA) coated with reduced graphene oxide (RGO) to be used for degradation of crude petroleum under simulated solar irradiation. The morphological studies of the functionalized textiles substrates were performed by using Scanning Electron Microscopy and Energy Dispersive X-ray Spectroscopy, which indicated an excellent dispersion and adhesion of nanoparticles of about 60% (atomic %Ti) on the textile fibers covered with RGO after washing. Ultraviolet-visible Diffuse Reflectance spectra suggest a reduction in the band gap energy of TiO2 up to 2.86 eV due to the presence of RGO. The functionalized textiles presented at least 60% of photocatalytic efficiency measured by Rhodamine B degradation, decreasing less than 12% after the rigorous washing. The excitation/emission Synchronous Fluorescence Spectroscopy and Fourier-transform Infrared spectroscopies demonstrated a great potential for photocatalytic degradation of the functionalized textiles substrates as the appearance of the hydroxyl, carboxyl, and the C-O bands confirm the photoinduced oxidation of the organic compounds implying with high prospects in petroleum and wastewater treatment areas. Moreover, this environmentally friendly, sustainable, and inclusive research work can be included in clean technologies, contributing to the novel socio-economic model recognized as "Green Recovery".
