A facile and potentially scalable synthesis route to obtain SnO2-carbon composites was developed. SnO2 nanoparticles were deposited on the surface of two types of graphitic carbon: a) commercial porous graphite (HG) and b) graphitic carbon nanostructures (GCN). The synthesis procedure consists of two simple steps: i) room temperature formation/deposition of SnO2 nanocrystals and ii) thermal tre...
A novel synthesis containing microwave-assisted HCl etching reaction and precipitating reaction is employed to prepare hierarchical hollow SnO2@TiO2 nanocapsules for anode materials of Li-ion batteries. The intrinsic hollow nanostructure can shorten the lengths for both ionic and electronic transport, enlarge the electrode surface areas, and improving accommodation of the anode volume change du...
SnO2 nanoparticles were dispersed on graphene nanosheets through a solvothermal approach using ethylene glycol as the solvent. The uniform distribution of SnO2 nanoparticles on graphene nanosheets has been confirmed by scanning electron microscopy and transmission electron microscopy. The particle size of SnO2 was determined to be around 5 nm. The as-synthesized SnO2/graphene nanocomposite exhi...
SnO2 nanowires were prepared on bare oxidized silicon, Au and SnO2 coated substrates by thermal evaporation of tin grains in argon atmosphere at 900°C. X-ray diffraction (XRD) and field-emission scanning electron microscopy (FE-SEM) were used to characterize the SnO2 nanowires. FE-SEM images indicated that the size of SnO2 nanowires depend on the type of substrate. Gas sensor was fabricated by ...
SnO2 films containing organized mesopores and nanocrystalline frameworks with easily removable surfactant templates were produced electrochemically using interfacial amphiphilic assemblies formed on the working electrode as a template.
A silica microparticle has been successfully employed as a nanoscaffold to self-organize porphyrin and C60 molecules on a nanostructured SnO2 electrode which exhibits efficient photocurrent generation.
Tin dioxide (SnO2) is a widely investigated lithium (Li) storage material because of its easy preparation, two-step storage mechanism and high specific capacity for lithium-ion batteries (LIBs). In this contribution, a phase-pure cobalt-doped SnO2 (Co/SnO2) and a cobalt and nitrogen co-doped SnO2 (Co-N/SnO2) nanocrystals are prepared to explore their Li storage behaviors. It is found that the m...
in this study, a specific ch4 sensor is fabricated based on interdigitated electrode that modified with core-shell of tungsten carbide/tin oxide (wc/sno2) nanoparticles by wet chemical method in different percents of carbon and tungsten. the morphology of wet chemical-synthesized wc/sno2 core-shell was evaluated by different methods such as patterned x-ray diffraction (xrd), and particle size a...
A novel binder-free graphene - carbon nanotubes - SnO2 (GCNT-SnO2) aerogel with vertically aligned pores was prepared via a simple and efficient directional freezing method. SnO2 octahedrons exposed of {221} high energy facets were uniformly distributed and tightly anchored on multidimensional graphene/carbon nanotube (GCNT) composites. Vertically aligned pores can effectively prevent the emers...
A Sn-SnO2/C nanocomposite was synthesized using the electrospinning method. Thermal analysis was used to determine the content range of Sn and SnO2 in the composite. The composite was characterized by X-ray diffraction, and the particle size and shape in the Sn-SnO2/C composite were determined by scanning and transmission electron microscopy. The results show that the Sn-SnO2/C composite takes ...
