Abstract:

Abstract Rare earth metal cerium-doped titania nanoparticles (titanium dioxide [TiO2]) were produced utilizing a low-cost and straightforward sol–gel technique, and its enhanced photodynamic anticancer activity was tested on Y79 retinoblastoma cancer cells. The structural, optical, morphological, anticancer activity, and cytotoxicity of pure and cerium-doped TiO2 (Ce-doped TiO2) were investigated. In X-ray diffraction (XRD) measurements, apparent doping of cerium in TiO2 was detected, with reported anatase patterns shifting toward a lower angle in the anatase structure.

Recent experiments have indicated that TiO2 co-doped with cerium (Ce) and nitrogen (N) may show enhanced photocatalytic activity in the visible region with respect to TiO2 doped only with Ce.

Density functional theory (DFT) calculations have been carried out with the generalized gradient approximation (GGA) to describe the electronic structure and photocatalytic activity of Ce-, N- and N/Ce-doped anatase TiO2; substitutional locations of Ce and N in the TiO2 lattice were considered: an O (Ti) atom

Abstract:

In this study, nano-cerium dioxide doped titanium-dioxide (CeO2-TiO2) Nanocomposites (NCs) was used for the photocatalytic degradation of pollutant parameters (color, polyphenols, polyaromatics) from a textile industry wastewater (TI ww) treatment plant located in Izmir, Turkey, at different operational conditions such as at increasing photocatalytic time (0, 10, 15, 20, 30, 60, 90 and 120 min), at different CeO2-TiO2 mass ratios (1%, 3%, 5%, 10%, 15%, 16%, 25%, 30%, 50%), at the different amounts of CeO2 (1, 3, 5, 8, 10, 15, 20 and 25 mg/L) under 130 W Ultraviolet (UV) and 35 W sun lights irr

Abstract:

Ca poisoning behavior is inevitable for high-calcium content flue gas, so V2O5-WO3/TiO2 (VWT) and V2O5-WO3-CeO2/TiO2 (VWCeT) catalysts with different vanadium content have been prepared and the Ca-doped catalysts are compared in this manuscript. The result shows Ce addition can both promote the NO conversion and the alkali resistance. Lower Ca addition for 0.1VWCeT catalyst promotes its oxidability and Ce modification is more suitable for low vanadium catalysts. The total acidity and the reducibility of catalysts decline after Ca doping, and the reducibility of the active species on catalysts

Abstract:

The threat of antibiotic resistance to the wellbeing of societies is well established. Urban wastewater treatment plants (UWTPs) are recognised sources for antibiotic resistance dissemination in the environment. Herein a novel cerium-doped zinc oxide (Ce-ZnO) photocatalyst is compared to ZnO and the benchmark TiO2-P25 in the immobilised form on a metallic support, to evaluate a photocatalytic process as a possible tertiary treatment in UWTPs. The catalysts were compared for the removal of two antibiotics, trimethoprim (TMP) and sulfamethoxazole (SMX), and for the inactivation of Escherichia co

Abstract:

Recently, aquatic life and human health are seriously threatened by the release of pharmaceutical drugs. For a sustainable ecosystem, emerging contaminants like antibiotics must be removed from drinking water and wastewater. To address this issue pure and cerium-doped titanium dioxide (CeT) nanoparticles were produced with stable tetragonal (anatase) lattices by room temperature sol–gel method and employing the inorganic titanium oxysulfate (TiOSO4) as titanium precursor. The structural analysis by X-ray diffraction (XRD) revealed that at calcination temperature of 600 °C all (un and doped) po
