|Title:||Photoabsorption and photocatalysis of SrSnO<inf>3</inf>produced by a cyclic microwave radiation|
Physics and Astronomy
|Abstract:||Rod-like hexagonal SrSn(OH)6precursors were produced by a cyclic microwave radiation (CMR) of a template-free solution containing SnCl2·2H2O and (CH3CO2)2Sr at the pH 12.2, adjusted by NaOH solution. The rod-like hexagonal SrSn(OH)6precursors were calcined at 500 °C, 700 °C and 900 °C for 3 h following the thermogravimetric analysis. In the end, the perovskite orthorhombic SrSnO3products in the shape of rods with 530 cm-1Sn-O stretching mode, characterized by X-ray diffraction, electron microscopy and Fourier transform infrared spectroscopy, were produced. UV-visible analysis of the best crystalline rod-like SrSnO3indicated an exponential decreasing of photonic absorption attenuated through the orthorhombic SrSnO3solid with 3.91 eV direct energy gap, including 85% decolorization efficiency under UV light for 320 min. © 2013 Elsevier Ltd.
