제목 Synthesis and Characterization Of Copper Doped Strontium Titanate (SrTiO3): Application to Methylene Blue Dye Degradation under Visible Light
초록 We report on the preparation of copper (Cu) doped SrTiO3 by sol-gel method via modified Pechini process for the methylene blue dye degradation. The morphological and physical properties of synthesized Cu doped SrTiO3 materials were characterization by X-rays diffraction (XRD), field-emission scanning electron microscope (FESEM), transmission electron microscope (TEM) and UV-DRS spectroscopy. From UV-DRS, the band gap was calculated of about 2.9 eV, which is lower than that of bare SrTiO3 (3.2 eV). It confirmed the Cu doping on the interstitial vacancy in SrTiO3 surface and showed a visible active material. The photocatalytic activity of the Cu doped SrTiO3 is measured by examine the degradation of methylene blue under visible light irradiation. It was observed that Cu-doped SrTiO3 degraded about 40% of methylene blue dye under visible light.
