X-ray powder diffraction data and refined unit cell parameters for three compounds found during experimental determination of the BaO:Fe2O3:TiO2 phase diagram are reported here. All three phases crystallize in space group C2/m (No. 12). Ba2Fe2Ti4O13 ("2:1:4") is isostructural with...
while the representative curve is shown inFig. 5a. During the cathodic scan process, each of the TiO2@Fe2O3arrays exhibits three reduction peaks around 1.75 V, 1.4 V and 0.8 V. The first peak is ascribed to the phase transition from tetragonal ...

TiO2 was more effective than Fe2O3 on the lowering of specific resistivity.It is concluded from these experimental results that the redox equilibria in the melts of 5Fe2O395RP2O6 and 7TiO293RP2O6 are expressed as, 2[XOx](2x-n-m)-=2Xn++(2x-m)O2-+m/2 O2where X is Fe or Ti...

The main purpose of this research endeavor is to reduce lead concentrations in the wastewater of an oil refinery through the utilization of a material composed of oyster shell waste (MIL-100(Fe)/Cygnea/Fe3O4/TiO2. Initially, iron oxide nanoparticles (Fe3
Alternatively, metal oxides, such as CuO, Cu2O, Fe2O3, WO3, MoO3, ZnO, SnO2, and so on, have been considered for band-gap engineering of TiO2 as these oxides have compatible processing strategies with TiO .297,328,436–444 2 Among these oxides, low band-gap CuO or Cu2O are ...
