Mesoporous SnO2 fibers have been prepared via precipitation of metal ions on green cotton template with further calcinations. The anode comprised of this novel SnO2 structure exhibites large reversible capacity and exceptional capacity retention ability. The improved electrochemical performance can be attributed to the large surface mesoporous netw...

Porous urchin-like α-Fe2O3 nanostructures with n-type semiconducting properties were used as gas sensing materials. Interestingly, it was observed abnormal n–p transition sensing behavior induced by the variation of working temperature and p–n transition sensing behavior related to the increase of H2S concentration. Large density of unstable surfac...

This paper firstly reported a simple route to prepare SnO2 mesoporous spheres for lithium ion battery. Mesoporous SnO2 spheres in range of 100–300nm were prepared by primary reaction at 353K for 30min, and calcination process at 773K, which could be scaled up for manufacturing. The nano-size effect of the small particle and the 3D mesoporous struct...

Mesoporous flower-like and urchin-like α-Fe2O3nanostructures have been successfully synthesized by a simple solution-based reaction and sequential calcination. Detailed experiments demonstrated that the morphology of the hierarchical α-FeOOH precursors could be easily controlled by adjusting the experimental conditions including reactant concentrat...

We reported a facile and efficient solution-based route to prepare novel flowerlike α-FeOOH architectures without any template or surfactant. Scanning electron microscope (SEM) images reveal that leaf-like nanosheets with a thickness about 40 nm assembled into flowerlike superstructures. On the basis of time-dependent experiments, a multistage reac...

Urchin-like nano/micro-structured Fe3O4/C composite has been successfully synthesized using inexpensive starting materials. The urchin-shaped nano/micro-structure consisted of several oriented nanorods. TEM analysis revealed that there is a large number of pores and uniform amorphous carbon distribution at a nanoscale in the nanorods walls. As used...

Carbon-coated magnetite dendrites (CMDs) were prepared by partial reduction of hematite dendrites (HDs) with carbon-coatings. CMDs were characterized by scanning electron microscopy, transmission electron microscopy, X-ray diffraction (XRD), and thermogravimetric analysis. The XRD results demonstrated the transformation of hematite to magnetite. As...

A facile chemical bath deposition (CBD) approach has been developed to fabricating SnS2 nanowall (NW) arrays directly on copper foils. As an anode material for lithium ion battery, the NW arrays exhibit enhanced lithium ion storage property. At a rate of 0.3 C, the NW arrays maintain a capacity of about 700 mA h g−1 after 40 cycles. Even at a high...

Porous one-dimensional Mn2O3 nanostructures have been successfully fabricated via a facile hydrothermal treatment and sequential thermal decomposition without any template or surfactant. By adjusting the ethanol content in the solvent system, nanofibers, nanowires and nanorods nanostructures can be selectively prepared. Moreover, corresponding poro...

Porous SnO2 nanotubes were prepared via electrospinning followed by calcination in air. As anode materials for lithium ion batteries, the porous nanotubes delivered a high discharge capacity of 807mAhg−1 after 50cycles. Even after cycled at high rates, the electrode still retained a high fraction of its theoretical capacity. Such excellent performa...
