چکیده
Abstract Strontium Titanate is a perovskite oxide with remarkable properties as photocatalyst. The synthesis of material Neodymium doping (Sr 0.97 Nd 0.03 TiO 3 ) has been completed by means the co-precipitation procedure. Samples were sintered at temperatures 900°C and 1000°C for 4 hours to investigate their properties. X-Ray Diffraction (XRD), Fourier-Transform Infrared spectroscopy (FTIR), UV-Vis Spectrophotometer employed observe microstructure, chemical bonds, photocatalyst activity Sr . XRD data exhibited that crystal size enlarged from 42.3 nm 64.4 sintering temperature increased. FTIR revealed strong Sr-Ti-O bonds decreased C-H C=H bond impurities photocatalytic performance was evaluated methylene blue (MB) dye degradation UV light irradiation 3, 4, 5 where spectrophotometer tested absorbance degraded MB. results achieved optimal (62.7%) irradiation.

متن کاملIntrinsic Mobility Limiting Mechanisms in Lanthanum-Doped Strontium Titanate
The temperature dependent Hall mobility data from La-doped SrTiO3 thin films are analyzed and modeled considering various electron scattering mechanisms. We find that a ∼6 meV transverse optical phonon deformation potential scattering mechanism is necessary to explain the dependence of transport on temperature between 10–200 K. Also, we find that the low temperature electron mobility in intrins...
