“…The absence of drops at the ends of nanobelts suggests that their growth is governed by a catalyst free process as the vapor-solid ͑VS͒ mechanism. [14][15][16][17] As pointed out by Sun et al 16 SnO 2 nanostructures grew by a VS mechanism in which SnO 2 ͑s͒ decomposes in SnO͑v͒ and CO 2 ͑v͒. The stannous oxide decompose in SnO 2 ͑s͒ and Sn͑l͒ giving origin to the final SnO 2 nanostructure.…”

The study of structures based on nonstoichiometric SnO 2−x compounds, besides experimentally observed, is a challenging task taking into account their instabilities. In this paper, we report on single crystal Sn 3 O 4 nanobelts, which were successfully grown by a carbothermal evaporation process of SnO 2 powder in association with the well known vapor-solid mechanism. By combining the structural data and transport properties, the samples were investigated. The results showed a triclinic semiconductor structure with a fundamental gap of 2.9 eV. The semiconductor behavior was confirmed by the electron transport data, which pointed to the variable range hopping process as the main conduction mechanism, thus giving consistent support to the mechanisms underlying the observed semiconducting character.

In this work, DESs were used as functionalizing agents for graphene due to their potential to introduce new functional groups and cause other surface modifications. Eighteen different types of ammonium-and phosphonium-salt-based DESs were prepared and characterized by FTIR. The graphene was characterized by FTIR, STA, Raman spectroscopy, XRD, SEM, and TEM.Additional experiments were performed to study the dispersion behavior of the functionalized graphene in different solvents. The DESs exhibited both reduction and functionalization effects on DES-treated graphene. Dispersion stability was investigated and then characterized by UV-vis spectroscopy and zeta potential. DES-modified graphene can be used in many applications, such as drug delivery, wastewater treatment, catalysts, composite materials, nanofluids, and biosensors. To the best of our knowledge, this is the first investigation on the use of DESs for graphene functionalization.

In comparison to other approaches, the solution method has its own advantages, such as low temperature, high production yield, and high quality.…”
