Incubation and aging effect on cassiterite type tetragonal rutile SnO2 nanocrystals

Abstract

The effect of incubation and aging on cassiterite type tetragonal rutile SnO 2 nanocrystals employing green synthesis technique has been investigated. The incubation and aging affected the compositional and morphological properties of SnO 2 and not influenced the structural properties of nanocrystals. The incubation and aging further influenced the particle shape and size of the obtained product. XRD results of the obtained product unambiguously revealed the cassiterite type tetragonal rutile phase of SnO 2 nanocrystals. The characteristic Raman peaks observed at 249, 476, 631 and 773 cm -1 were respectively revealed infrared active (E u ), Raman active (E g ), (A 1g ) and (B 2g ) vibration modes of pure tetragonal rutile SnO 2 structure. 3d 3/2 and 3d 5/2 of XPS peaks observed at 496 and 487 eV was clearly revealed the Sn 4? state in tetragonal rutile structure. The obtained TEM micrographs clearly revealed that the grain size and agglomeration was increased at higher incubation and aging treatments.

Synthesis and structural characterization of gallium oxide powders

“…In the present study, the inorganic complex intermediate green ligation from natural waste resources has been adopted to synthesis gallium oxide powders [13][14][15][16][17][18][19][20][21]. Among many synthetic methods, metal-ellagate square planar complex method is the simple technique to prepare bio inspired transition metal oxide powders.…”

Structural characterization of beryllium and indium oxide powders

“…In the present study, we report on the structural properties of beryllium and indium oxide powders using a sustainable green synthesis method without surfactant and template at room temperature incubation and aging over a period of 7 days for sustainable materials development. Therefore, in the present study, metal-ellagate square planar complex method is employed to prepare metal oxide powders [36][37][38][39][40][41][42][43][44]. The obtained metal-ellagate complex has been decomposed into BeO and In 2 O 3 powders by calcinating in static air atmosphere at 350, 500 and 650°C for 1 h.…”
