Abstract:
In the present study, the photocatalytic activity of catalysts TiO2-SiO2 composite (TiO2-S) was studied and evaluated by the degradation of organic pollutants such as methylene blue (MB) under UV irradiation. The TiO2-S composite with ratios of 75:25%wt and 66:34%wt was synthesized by the sol-gel method, to compare the performance of TiO2 and SiO2 particles prepared with a microwave-assisted method. The TiO2-S photocatalysts were studied by using a Scanning Electron Microscope (SEM), Transmission electron microscopy (TEM), Energy Dispersive X-ray Spectrophotometer (EDS), X-Ray Photoelectron Spectroscopy (XPS), and X-ray Diffraction (XRD). In addition, the efficacy of the TiO2-S photocatalyst in MB degradation compared to other catalysts was 97-98% at 40 min under UV irradiation.
The research is also interested in the use of polymer catalyst support. Due to the use of non-biodegradable polypropylene (PP) plastic bags, it is therefore recycled these to support synthetic TiO2-S nanocomposites. The degradation efficiency of MB dyes and volatile fatty acids (VFAs) were assessed under UV irradiation and analysed by gas chromatography-mass spectrometry (GC-MS). The results showed that TiO2-S can degrade the organic compounds and can be used in a wide range of applications for polymer-coated products, such as shoe insoles to reduce the unpleasant smell from VFAs in the future
