With the objective of developing new advanced composite materials that can be used as anodes for lithium ion batteries (LIBs), herein we describe the synthesis of a novel three dimensional (3D) macroporous foams formed by reduced graphene oxide (rGO) and submicron tin-based particles. The aerogels were obtained by freeze/freeze-drying a suspension of graphene oxide (GO) in the presence of a tin...

Electrochemical-oxidation of Reactive Black-5 (RB5) was conducted for degradation using DSA type Ti/RuO2-SnO2Sb2O5 electrode. In the study, for electro-oxidation, electrode was indigenously fabricated in laboratory using titanium as substrate. This substrate was coated using different metal oxides RuO2, Sb2O5 and SnO2 by thermal decomposition method. Laboratory scale batch reactor was used for ...

The objective of the work presented here is to estimate characteristics power balance, i.e., and surface density that electric arc brings silver–tin oxide (Ag–SnO2) electrodes. This first based on an experimental study carried out using IR camera with which we measured temperature in a zone close area impacted by arc, but not flashed it. In second step, distributions obtained are compared resul...

Highly porous surface fluorinated SnO2 hollow nanospheres (SnO2(F) HNS) were produced in high yield by a hydrothermal treatment of stannous fluoride in the presence of hydrogen peroxide. Two important processes in terms of oriented self-assembly and in situ self-transformation were highlighted for the formation of as-prepared SnO2(F) HNS, which were largely relying on the directing effects of s...

Single crystalline tin oxide (SnO2) nanowires have been synthesized by carbothermal reduction of SnO2 nanopowder followed by thermal evaporation of the reduced precursor and growth via the vapor-liquid-solid (VLS) growth mechanism. The nanowires are deposited on single crystalline TiO2 substrates of orientations of (100) and (110) that are coated with a thin film and colloids of gold (Au) catal...

Polarization-dependent X-ray absorption measurements reveal the existence of structural anisotropy in amorphous (a-) SnO2 film. The anisotropy is readily seen for the second neighbor interaction whose magnitude differs along three measured directions. The differences can be well accounted for by 10%–20% variation in the Debye-Waller factor. Instead of a single Gaussian distribution found in cry...

It is important to improve the sensitivities and selectivities of metal oxide semiconductor (MOS) gas sensors when they are used to monitor the state of hydrogen in aerospace industry and electronic field. In this paper, the ordered mesoporous SnO2 (m-SnO2) powders were prepared by sol-gel method, and the morphology and structure were characterized by X-ray diffraction analysis (XRD), transmiss...

We demonstrated highly efficient inverted bottom-emission organic light-emitting diodes (IBOLEDs) using tin dioxide (SnO2) nanoparticles (NPs) as an electron injection layer at the interface between the indium tin oxide (ITO) cathode and the organic electron transport layer. The SnO2 NP layer can facilitate the electron injection since the conduction band energy level of SnO2 NPs (-3.6 eV) is l...
