Ordered mesostructured Cu-doped TiO2 spheres as active visible-light-driven photocatalysts for degradation of paracetamol

The advanced removal of benzene from aerosols by photocatalytic oxidation and adsorption of Cu–TiO 2 /PU under visible light irradiation

“…This observation also indicates that the Cu dopants incorporated into the TiO 2 lattice, leading to distortions in the crystal lattice. Cu dopants could defect and sub- stitute the Ti 4+ ions in the TiO 2 lattice by forming Cu O Ti bonds [29,38]. Due to the incorporation of Cu into the TiO 2 lattice, the interlayer distance of the (1 0 1) crystal plane of the TiO 2 anatase also slightly increased ( Fig.…”

Advanced removal of C. famata in bioaerosols by simultaneous adsorption and photocatalytic oxidation of Cu-doped TiO 2 /PU under visible irradiation

“…CuO in Cu-TiO 2 /PU was produced from thermal decomposition of Cu(NO 3 ) 2 during UV irradiation or calcination processes [22]. The UV irradiation (photo-reduction) and oxalic acid, rolled as a cleaner for the cleaning process, could reduce Cu 2+ into Cu + during the decomposition of Cu(NO 3 [34]. The substitution of Cu 2+ into TiO 2 lattice was confirmed by XRD analysis (see Supplementary material).…”

Remediación de aguas contaminadas, utilizando dióxido de titanio modificado con hierro como fotocatalizador.

“…Del estudio de caracterización de fisisorción con nitrógeno, se deduce que las isotermas obtenidas para todas las muestras corresponden a isotermas tipo IV, las cuales son características de materiales mesoporosos (Jung Li, C., 2013). En cuanto al tamaño de esos poros, y el área específica de cada sólido, se presentan los valores en la siguiente tabla.…”
