“…Combining catalysis with renewable energy resources, however, as in solar photocatalysis, is expected to cut down treatment costs and make AOPs more attractive to the water industry. 18 An example of treatment of washing waters from pesticide containers is provided by a plant in Almería (Spain) that uses solar energy. 19 Another is the Mané Garrincha Stadium in Brasília (Brazil), renovated for the 2014 FIFA World Cup and often cited as a sustainable building for its self-cleaning roof consisting of a TiO 2 -coated polytetrafluoroethylene membrane.…”

This article reports the synthesis and characterization of pure and N-, B-, and Ag-doped TiO 2 and the ability of these oxides to photodegrade methylene blue (MB) under sunlight or UV-ABC radiation. The compounds were synthesized using the sol-gel method and characterized by scanning electron microscopy, X-ray diffraction, diffuse reflectance spectroscopy, Fourier transform infrared spectroscopy, thermogravimetric analysis, and X-ray photoelectron spectroscopy. Photocatalytic efficiency was significantly increased by N-doping, resulting in 98% MB decomposition under UV-ABC irradiation for 180 min. Ag-and B-doped TiO 2 lowered MB degradation rates to 52 and 73%, respectively, compared with pure TiO 2 . The same behavior was observed with exposure to UV-Vis, with 88, 65, 60, and 42% MB removal with N-doped, pure, B-doped, and Ag-doped TiO 2 , respectively. Under visible light alone, N-doped TiO 2 exhibited higher photocatalytic efficiency than commercial P25-type TiO 2 . Photocatalysis with N-doped TiO 2 proved to be a promising alternative for MB degradation, given the potential of employing solar energy, thus minimizing operating costs.

“…The literature shows that for the determination of some anti-inflammatory compounds by chromatographic method there is a need to use buffer solutions [13] [19] [20]. The present developed method used to identify and quantify IBF does not use buffer solution and the present method was validated as shown.…”

Several pharmaceutical compounds have been detected in natural aqueous systems and ibuprofen (IBF), one of the most consumed medicament, has been detected in many countries. The degradation efficiency of IBF under TiO2/UV radiation was evaluated. Optimum degradation results were observed using 20 mg•L −1 of TiO2, pH 7.8 and 5 mg•L −1 of IBF. Under these experimental conditions total IBF removal was achieved in less than 60 min of irradiation. Although total IBF concentration was observed, the total mineralization of the compound was not achieved. The by-products generated during TiO2/UV reaction showed to be more toxic against Daphnia similis than the initial IBF present in aqueous solution.

3D printing technology has become a powerful tool to produce 3D structures in any type of materials. In this work, 3D printing technology is used to produce 3D porous structures in CaSO 4 which can be later activated with an appropriate photocatalyst. TiO 2 was selected as an ideal photocatalyst producing activated 3D structures which can be used to study their effectiveness in the degradation of pollutants in wastewater. Methylene blue was used as a model molecule in these studies. The photocatalytic studies showed that TiO 2 -activated 3D structures using nanoparticles of SiO 2 in the process produce more than 50% of conversion of methylene blue in just 1 h of irradiation and almost 90% in 5 h.
