Macroporous SnO2 (mp-SnO2(P-n); P means polymethylmethacrylate (PMMA) and n = diameter of PMMA microsphere) thick film gas sensors were fabricated by a modified sol-gel method by employing PMMA microspheres (n = 800, 400, 250 and 150 nm) as a template and SnCl2 as a tin source. Morphology of mp-SnO2 films was markedly dependent on the SnCl2 concentration and the diameter of PMMA microspheres. E...

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...

Chestnut-like SnO2 and SnO2/C nanocomposites with hierarchical structures are synthesized by hydrothermally oxidizing Sn nanoparticles in glucose solution. Structural characterizations using SEM and TEM reveal that the SnO2 nanoparticles are composed of numerous, randomly arranged SnO2 nanosheets with hollow cores. Owing to the short electron and ion diffusion distances and transformation strai...

cofe/cu multilayer nanowires were electrodeposited into anodic aluminum oxide templates prepared by a two-step mild anodization method, using the single-bath technique. nanowires with 30 nm diameter and the definite lengths were obtained. the effect of cofe layers thickness and annealing on the magnetic behavior of the multilayer nanowires was investigated. the layers thickness was controlled t...

In this paper, hierarchical Ag-decorated SnO2 microspheres were synthesized by a facile one-pot hydrothermal method. The resulting composites were characterized by XRD, SEM, TEM, XPS, BET, and FTIR analysis. The catalytic performances of the samples were evaluated with the reduction of 4-nitrophenol to 4-aminophenol by potassium borohydride (KBH4) as a model reaction. Time-dependent experiments...

SnO2 microspheres with controllable morphology were prepared via a hydrothermal-annealing method. The SnO2 morphology can be tuned by using AlOOH sol and g-Al2O3 as additive. The hollow SnO2 microspheres with incomplete core-shell structure prepared with small amount of g-Al2O3 presented the best cycling performance in Li-ion battery, exhibiting a specific capacity of 374.2 mAh g 1 up to 100 cy...

High oxygen evolution overpotential and inexpensive Ti/Co3O4/PbO2/(SnO2+Sb2O3) and (Ti/(SnO2+Sb2O3) electrodes were investigated in this work. These electrodes were prepared and used as anodes for removal of Reactive Black 5 (RB5) dye in aqueous solution. In some local cases in Palestine, wastewater color was found to be the only problem in meeting local effluent standards. This investigation r...

The Fe nanowires were prepared by Ac electrodeposition method. The two steps anodized aluminum oxides (alumina) were used as templates for electrodeposition of magnetic nanowires. Sulfuric acid was used to anodize aluminum. The pours diameter and growth rate of alumina were investigated. The FeSO4 electrolyte was used for growth of nanowires. The prepared magnetic nanowires were characterized b...

Novel SnO2/SiC hollow sphere nanochains were synthesized by topological morphology conversion of SnO2@C core-shell nanochains through a vapour-solid reaction. Evaluation of the SnO2/SiC HSNCs for the generation of hydrogen revealed that they exhibit excellent catalytic activity and durability.
