This study assessed 3D WO3–TiO2 nanoflowers (WTNF) synthesized by a combined hydrothermal–ultrasonication–impregnation method for their applicability to the treatment of aromatic volatile compounds under visible-light illumination. The scanning electron microscopy exhibited the formation of 3D structures in the prepared WTNF samples. The X-ray diffraction patterns and energy dispersive X-ray re...

The photocatalytic performances of doped and non-doped TiO2 photocatalysts (TiO2-s) were compared under solar various types artificial irradiation using phenol as a model contaminant. Non-doped (mainly anatase phase) TiO2-s had significantly higher efficiency than highly visible-light-active natural irradiation. To explain these unexpected results, we measured the wavelength dependence at six d...

Poly vinyl acetate (PVA)-based titania (TiO2)–carbon nanotube composite nanofibers (PVA-TCCNs) with various PVA-to-solvent ratios and PVA-based TiO2 composite nanofibers (PVA-TN) were synthesized using an electrospinning process, followed by thermal treatment. The photocatalytic activities of these nanofibers in the degradation of airborne monocyclic aromatics under visible-light irradiation we...

introduction: textile industries produce large volume of colored dye effluents which are toxic and removal of dyes from wastewater is a significant environmental issue. advanced oxidation process (aops) is alternative method for the complete degradation many organic pollutants. zno and tio2 are important photocatalysts with high catalytic activity that have attracted much research attention. ma...

Impurity doping is a simple and efficient modification method to improve the photocatalytic performance of wide band gap photocatalysts. However, some basic and important issues about the mechanism of impurity doping modification still need to be further confirmed and explained. In the present work, Pr-doped TiO2 with a mono-phase crystal structure was prepared by a sol-gel method. Then, the cr...

The whole world is struggling with current coronavirus pandemic that shows urgent need to develop novel technologies, medical innovations or innovative materials for controlling SARS-CoV-2 infection. mode of infection still not well known and seems spread through surface, air, water. Therefore, the surrounding environment needs be disinfected continuous function. For purpose, excellent antivira...

A single-step impregnation approach is investigated as a synthetic route for photocatalyst synthesis active under visible light. The as-derived photocatalysts exhibited very high degradation rates towards methylene blue (MB) decolorization light despite the concentration of initial MB solution concentration. TiO2-based were prepared using nitrate precursor compounds copper and silver; thus, Ag/...
