The indiscriminate use of naproxen as an anti-inflammatory has been the leading cause pollution in sewage effluents. Conversely, titanium dioxide is one most promising photocatalyst for degradation pollutants. Ti-La mixed oxides containing 0, 1, 3, 5, and 10 wt.% lanthanum were synthetized by sol-gel tested photocatalysts (NPX). materials further characterized X-ray diffraction (XRD), nitrogen ...

Ni/oxide-SiO2 (oxide: MgO, CeO2, La2O3, 10 wt.% target concentration) catalyst samples were prepared by successive impregnation of silica matrix, first with supplementary oxide, and then Ni (10 concentration). The matrix multimodal pore structure was solvothermal method. structurally characterized N2 adsorption-desorption, XRD, SEM/TEM, functionally evaluated temperature programmed reduction (T...

An efficient and simple protocol for synthesis of novel La(2)O(3) hollow nanospheres of size about 30 ± 2 nm using polymeric micelles is reported. The La(2)O(3) hollow nanospheres exhibit high charge capacity and cycling performance in lithium-ion rechargeable batteries (LIBs), which was scrutinized for the first time among the rare-earth oxides.

Isothermal section of the Al2O3–TiO2–La2O3 phase diagram at 1400 °C is constructed for first time. It part systematic investigations Al2O3–TiO2–Ln2O3 (Ln = lanthanides, Y) systems. The was taken as temperature, which no liquid expected in system. Samples were prepared by a chemical method. annealed air 80 hour sand cooled furnace. Phases samples determined XRD analysis. New phases and appreciab...
