Photocatalytic performance of textiles coated with TiO2-RGO system for degradation of crude petroleum under similar solar irradiation
The pollution caused by oil and its toxic derivatives presents a considerable risk to the
public health and the environment. Here, we studied the influence of TiO2 nanoparticles
immobilized on three types of textiles materials (Cotton, Entretela and 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 on the textile fibres covered with RGO. Ultraviolet–visible Diffuse
Reflectance spectra suggests a reduction in the band gap energy of TiO2 due to the
presence of RGO. The excitation/emission Synchronized Fluorescence and Fourier transform Infrared spectroscopies demonstrated that the functionalized textiles substrates
exhibit a great potential for photocatalytic degradation of organic compounds with high
prospects in petroleum and wastewater treatment areas
