“…The dielectric constant of the solvent plays a crucial role on the morphology and structural properties of TiO 2 after the nucleation of primary particles. 27 It was observed in our study that ethanol play vital role in the final spherical shape formation of the mesoporous TiO 2 . In absence of ethanol, the particles were aggregated to form the secondary particles but no definite shape.…”

Mesoporous TiO 2 microspheres with high specific surface areas were synthesized by means of a facile one-step microwave hydrothermal process without using any template. The mesoporous materials were rapidly achieved using TiCl 4 , urea and ammonium sulphate at comparatively low microwave power (400 W) for 8 min irradiation. The morphology and microstructure of the as-prepared products were characterized by field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), transmission electron microscopy (TEM) and Brunauer-Emmett-Teller (BET) surface area analysis. Structural characterization indicates that the TiO 2 microspheres display mesoporous structure. The average pore sizes and BET surface areas of the spheres were 5.3 nm and 222 m 2 g -1 , respectively. The mesoporous nanocrystals synthesized at 160°C for 8 min were then used to prepare the photoanode for dye sensitized solar cells (DSSCs). A high power conversion efficiency of 5.72% was achieved from the mesoporous TiO 2 based photoanode, representing about 25.7% improvement over the efficiency of P25 photoanode.

In this research, nanostructured SnO 2 materials have been prepared via thermal treatment method with the aid of new Schiff base complex. N,N 0 -bis(salicylidene)-1,2-propylenediamine (H 2 salpn) has been used as Schiff base to prepare a new Schiff base complex. The products were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy and TEM. Then, as-prepared SnO 2 nanoparticles have been applied as working electrode in dye-sensitized solar cells sensitizing with two different natural dyes: madder and mignonette.

“…Among the binary metal oxide, tin dioxide (SnO 2 ) is a wellknown large band gap multifunctional material that found widespread applications in the fields of lithium rechargeable batteries [4], gas sensors [5][6][7], and photovoltaic conversion [8][9][10]. Because of the more positive conduction band (CB) edge, SnO 2 is a better electron acceptor than TiO 2 and ZnO [11,12] that makes it a good potential candidate in the field of photocatalysis.…”

Tin dioxide (SnO 2 ) behaves excellent properties, but the high recombination rate of photoexcited electron-hole pairs combined with a large band gap restricts its photocatalytic applications. Comparing with pure SnO 2 nanospheres, the photocatalytic degradation of rhodamine B (RhB) over polymer/reduced graphene oxide (rGO)/SnO 2 composites was enhanced. For the synthesis, graphene oxide (GO) nanosheets were wrapped on the surface of polymer microspheres to form a polymer/GO core-shell structure. Then, SnO 2 nanospheres were decorated on polymer/GO microspheres under a hydrothermal condition, meanwhile GO was reduced to rGO. Therefore, polymer/rGO/SnO 2 hierarchical structure was obtained. As graphene promote separation of the photoexcited electron-hole pairs and the conduction band potential of SnO 2 is more positive than the work function of graphene, electrons can be quickly transferred to the conduction band of SnO 2 via graphene leaving over more holes on the surface of catalyst for the de-ethylation of RhB.
