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. Raman spectra verify th

Abstract:

butyl titanate, water and anhydrous ethanol were used as raw materials; Cerium-doped TiO2 was prepared by sol method at room temperature. Then it was characterized by X ray diffraction, Raman spectra, Uv-vis absorption spectra and Scanning Electron Microscope. The results show that TiO2 crystal can be got by sol method at room temperature. Cerium-doped TiO2 has the better catalytic performance for methyl orange.

Abstract:

Organic contaminants of various classes can be degraded and completely mineralized by titania based photocatalysis. Cerium doped microporous crystals with different amount of Ce (0.3, 0.5,0.7 and 1.0%) were synthesized via a hydrothermal process. The cerium doped TiO2 nanoparticles were characterised by X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM). The degradation of thiamethoxam was investigated under artificial light (mercury lamp) in the laboratory. The effect of some parameters like pH, catalyst amount, concentration of pesticides and intensity of light w

Abstract:

Cerium and nitrogen co-doped TiO2 nanocrystals were synthesized by a simple sol-gel process, using tetrabutyl titanate as the raw materials with (NH4)2Ce(SO4)3 and urea as ion donors. The co-doped TiO2 nanoparticles were characterized by X-ray diffraction and transmission electro microscopy. The photodegradation of glyphosate has been investigated in aqueous suspensions of doped TiO2 under visible irradiation. The results exhibit a higher thermal stability of anatase than pure TiO2.The uniform test results show the optimal conditions: nCe/nTi nN/nTi and calcining temperature was 0.08,0.01 and

Abstract:

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. Prompted by these findings, we have investigated Ce-N co-doped TiO2 through a theoretical study. 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:

Doped and undoped titanium dioxide films have been deposited on indium tin oxide glass using the sol-gel technique. The percentage of rutile in the prepared TiO2, calcined at 823 K and determined by X-ray diffraction, was 23% compared to 24% of rutile in P25-TiO2. Cerium doped TiO2 showed mainly the anatase phase, as characterised by both X-ray diffraction and Raman spectroscopy. The electrochemical and photoelectrochemical properties of the films were studied by cyclic voltammetry and electrochemical impedance spectroscopy. The (photo)electrochemical characteristics of the different films are

Abstract:

This experiment aims to prepare the Zn2 +-doped TiO2 composite semiconductor materials by the sol-gel method and to characterize their crystal structures by X-ray diffraction and electron microscopy (SEM) scanning. The degradation target in this experiment is the pharmaceutical wastewater of a certain Chinese patent medicine, whose COD is as high as 300,000 mg/L and chroma is above 500 degrees. When the doping ratio of ZnO is 8%, the pharmaceutical wastewaters COD and chroma removal rates for 2hs degradation respectively reach 72.5% and 33.8%.

Abstract:

Cerium element with a unique electric structure can be used to modify semiconductor photocatalysts to enhance their photocatalytic performances. In this work, Ce-doped TiO2 (Ce/TiO2) was successfully achieved using the sol-gel method. The structural characterization methods confirm that Ce was doped in the lattice of anatase TiO2, which led to a smaller grain size. The performance test results show that the Ce doped in anatase TiO2 significantly enhances the charge transport efficiency and broadens the light absorption range, resulting in higher photocatalytic performance.
