“…Nanostructures of VO 2 powder also have been prepared using a number of techniques. These mainly include the reduction of KVO 3 with KBH 4 [15], pyrolysing of the Vanadium containing precursor [16], sol-gel method and hydrothermal synthesis method. Among them, the solution-based strategies seemed to be promising for the large-scale synthesis of VO 2 nanostructures.…”

“…1 that the trend and characteristic peaks of ZnO-SL are in good agreement with that of ZnO, which indicates that the crystal structure of ZnO-SL was not affected by the SL [23]. Compared to ZnO, the infrared spectrum of ZnO-SL showed a red shift (the peak from 1629 cm -1 of ZnO to 1586 cm -1 of ZnO-SL)and the peak broadening phenomena, which indicates that the ZnO-SL particle size becomes smaller [24].…”

Flower cluster-shaped ZnO microstructures have been successfully synthesized by a facile hydrothermal approach without further heat treatment using Zn(NO 3 ) 2 . 6H 2 O and NaOH as raw materials and sodium lignosulfonate (SL) as a structure-directing agent. The morphology, structure, and property of the products were characterized by X-ray powder diffraction, fourier transform infrared spectroscopy, scanning electron microscopy, Brunauer-Emmett-Teller nitrogen adsorption-desorption isotherms and photoluminescence spectrum. The photocatalytic activity of the as-prepared samples were evaluated by photocatalytic decolorization of methylene blue aqueous solution at ambient temperature. The results indicated that the prepared ZnO-SL sample exhibited flower clustered morphology, hexagonal wurtzite structure, higher surface areas and better UV and visible photocatalytic activity. Moreover, the ZnO-SL sample showed excellent stability after three photodegradation cycling runs.

“…5A show that there were two modi"cations of IR spectra from bulk crystals to "ne crystals: the absorption wavenumbers are lowered gradually, the absorption at 494&518 cm\ disappeared gradually. This phenomenon was observed in the amorphism (17,18) and gels (19) of V O , also observed in amorphous and nano-crystalline VO powder (11). The size e!ect of crystalline V O (19,20) can be associated with the huge surface of material.…”

“…The choice of this precursor is based on the following considerations that it is easily synthesized (11) and that nanocrystal V O is expected to be easily obtained due to the releasing of a large amount of gases during pyrolysis. Advantages of this approach includes the ability to easily generate nanocrystal V O at low production cost and high production rate using commercial V O as a starting material (11).…”
