Photoabsorption and photocatalysis of SrSnO<inf>3</inf>produced by a cyclic microwave radiation
Rod-like hexagonal SrSn(OH) 6 precursors were produced by a cyclic microwave radiation (CMR) of a template-free solution containing SnCl 2 ·2H 2 O and (CH 3 CO 2 ) 2 Sr at the pH 12.2, adjusted by NaOH solution. The rod-like hexagonal SrSn(OH) 6 precursors were calcined at 500 °C, 700 °C and 900 °C...

| Summary: | Rod-like hexagonal SrSn(OH) 6 precursors were produced by a cyclic microwave radiation (CMR) of a template-free solution containing SnCl 2 ·2H 2 O and (CH 3 CO 2 ) 2 Sr at the pH 12.2, adjusted by NaOH solution. The rod-like hexagonal SrSn(OH) 6 precursors were calcined at 500 °C, 700 °C and 900 °C for 3 h following the thermogravimetric analysis. In the end, the perovskite orthorhombic SrSnO 3 products in the shape of rods with 530 cm -1 Sn-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 SrSnO 3 indicated an exponential decreasing of photonic absorption attenuated through the orthorhombic SrSnO 3 solid with 3.91 eV direct energy gap, including 85% decolorization efficiency under UV light for 320 min. © 2013 Elsevier Ltd.
