“…Intensive work is currently underway on various combinations of TiO 2 NPs with other inorganic elements and compounds to improve their photochemical properties. Kayani et al developed cerium-doped (Ce-doped) TiO thin films synthesized by the sol-gel dip-coating route [47]. The band gap of the Ce doped TiO 2 slightly decreased from~3.93 eV to~3.79 eV with an increase in Ce doping percentage.…”

“…Following the results, the NPs did not reveal any photodynamic activity even when the amount of the compound increased (16 mg/mL) in agar medium. This can be also associated with the problems that appeared during the measurements as the tested NPs precipitated in the agar and did not mix properly with the agar medium [47]. The anti-cancer activity of modified and unmodified titanium(IV) oxide NPs has also recently been studied by Shah et al [48].…”

Metallic and metal oxide nanoparticles (NPs), including titanium dioxide NPs, among polymeric NPs, liposomes, micelles, quantum dots, dendrimers, or fullerenes, are becoming more and more important due to their potential use in novel medical therapies. Titanium dioxide (titanium(IV) oxide, titania, TiO2) is an inorganic compound that owes its recent rise in scientific interest to photoactivity. After the illumination in aqueous media with UV light, TiO2 produces an array of reactive oxygen species (ROS). The capability to produce ROS and thus induce cell death has found application in the photodynamic therapy (PDT) for the treatment of a wide range of maladies, from psoriasis to cancer. Titanium dioxide NPs were studied as photosensitizing agents in the treatment of malignant tumors as well as in photodynamic inactivation of antibiotic-resistant bacteria. Both TiO2 NPs themselves, as well as their composites and combinations with other molecules or biomolecules, can be successfully used as photosensitizers in PDT. Moreover, various organic compounds can be grafted on TiO2 nanoparticles, leading to hybrid materials. These nanostructures can reveal increased light absorption, allowing their further use in targeted therapy in medicine. In order to improve efficient anticancer and antimicrobial therapies, many approaches utilizing titanium dioxide were tested. Results of selected studies presenting the scope of potential uses are discussed in this review.

“…Numerous catalyst have been investigated for dye degradation such as TMDSc-graphene, polyethylene-TiO2, Hollow cobalt NPs,Si/Six core shell nanowires, Sns nano particles, silver nanoparticles etc. [16][17][18][19][20]. However, these compounds have some disadvantages e.g., limiting by its UV activation, or complexity in synthesis process, however these compounds have some disadvantages e.g., limiting by its UV activation, or complexity in the synthesis process, consequently new compounds (i.e., Perovskites materials) recently developed to overcome these difficulties, and widely used for environmental pollution.…”

In this work, it was highlighted synthesis strategy and fundamental characterization of the pure and Ce doped Ba2TiMoO6 with different Ce concentrations were presented. It was investigated its thermal stability by using the Thermal Gravimetric Analysis and Differential Thermal Analysis. The crystal structures and the purity of the compounds were analyzed by X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy. The Surface morphology was examined by using Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM) and surface area analysis. The optical properties were examined by using the UV-Vis diffuse reflectance and photoluminescence (PL) spectroscopies. The prepared Ba2TiMoO6 nanopowders are characterized by band gap of 3.41~3.6 eV and violet emission of 426.67 nm wavelength. The degradation efficiency was found approximately 16% of Methyl Blue (MO) after 120 min duration. Our results will predicate new Perovskites materials, which can be used for future environmental applications.
