Influence of synthesis conditions on carbonate entrapment in perovskite SrSnO3

Simple synthesis and characterization of SrSnO3 nanoparticles with enhanced photocatalytic activity

“…In case of the SSSrSnO 3 powder, the Raman spectrum is in agreement with Zhang's previously reported result [11] in terms of the active modes of SrSnO 3 located at 119, 150, 168, 220, 257, 305, 403, 511, 596, 713 and 890 cm À1 . On the other hand, the Raman spectrum of SrSnO 3 nanoparticles is very different from that of SS-SrSnO 3 and bears more resemblance to Alves's result [20,21] where bands appear at 93, 108, 119, 152, 186, 227, 250, 261, 406, 577, 703 and 986 cm À1 . This difference has relevance to the incorporation of carbonate anions into the SrSnO 3 structure.…”

“…Some studies have reported that the incorporation of carbonate ions happens easily during the synthesis of some metal oxides and thus, various attempts [22,23] have been made to interrupt this incorporation. In particular, it has been reported that SrSnO 3 also shows this phenomenon [20,21]. In this case, carbonates ions replace O 2À anions in the SrSnO 3 crystal structure and are connected to Sr 2þ cations.…”

Decolorization of Methylene Blue by Ag/SrSnO3 Composites under Ultraviolet Radiation

“…SrSnO 3 has been synthesized by different methods such as solid state reaction at a temperature above 1,000 ∘ C [2], hydrothermal method [3,4], microemulsion [9], and polymeric precursor method [10]. Recently, microwave radiation has been used for the synthesis of materials, including inorganic complexes, oxides, and sulfides.…”

Nano cube of CaSnO3: Facile and green co-precipitation synthesis, characterization and photocatalytic degradation of dye

“…Without calcination process the product of reaction is cm -1 are accountable to bending modes of different hydroxyl groups on the surface of the product that appears in the definitive product at 1350 cm -1 . The vibrations of the stannate group (SnO2 -3 ) have been detected as high-intensity bands in the 300-400 and 600-700 cm -1 ranges, including the stretching vibration of the Sn-O bond at 530 cm -1 [22][23][24]. In this work, the calcined products have been detected at 670 cm -1 with high intensity.…”
