SnO2 is widely used for ethanol-sensing applications due to its excellent physicochemical properties, low toxicity and high sensitivity. However it a challenge construct 3D-hierarchical structures with sub 5 nm primary grain particle, which the optimized size ethanol sensor. Herein, genetic tri-level hierarchical microstructures are synthesised by conversion of 3D SnS2 flowers assembled ultrath...

A novel sponge-like porous C/Sn composite is synthesized by dispersing SnO2 nanoparticles into a softtemplate polymer matrix followed by carbonization. The mesoporous C/Sn anodes can deliver a capacity as high as 1300mAh g 1 after 450 charge/discharge cycles, and provide a capacity of 180mAh g 1 even at 4000 mA g 1 charge/discharge current density. An extra reversible capacity over the theoreti...

The as-synthesized nanowires and nanobelts usually have a large size distribution. We demonstrate here a ball milling technique for narrowing the size distribution of oxide nanobelts and nanowires. High-resolution scanning and transmission electron microscopy reveals that the one-dimensional SnO2 nanostructures with size .150 nm are sensitive to the milling effect and most of them were fracture...

We successfully synthesized large-scale and highly pure ultrathin SnO2 nanosheets (NSs), with a minimum thickness in the regime of ca. 2.1 nm as determined by HRTEM and in good agreement with XRD refinements and AFM height profiles. Through TEM and HRTEM observations on time-dependent samples, we found that the asprepared SnO2 NSs were assembled by “oriented attachment” of preformed SnO2 nanopa...

The crystal structures of different forms of TiO2 and those of BaTiO3, ZnO, SnO2, WO3, CuO, Fe2O3, Fe3O4, ZrO2 and Al2O3 nanoparticles have been deduced by powder X-ray diffraction. Their optical edges have been obtained by UV-visible diffuse reflectance spectra. The photocatalytic activities of these oxides and also those of SiO2 and SiO2 porous to oxidize iodide ion have been determined and c...

The morphology-controlled synthesis of SnO2 hollow/nanoporous nanostructures (nanotubes, urchin-like morphologies and nanospheres) was achieved via a template-engaged replacement reaction at a mild temperature (lower than 80 °C). The formation mechanism of hollow interior and nanoporous walls for the obtained SnO2 nanostructures (SnO2 nanotubes were used as an example) was investigated based on...
