An attempt has been carried out here to use nanoconic TiO2 hollow spheres as buffers accommodate the volume expansion of high-capacity materials. Based on spheres, we tailor-designed a novel composite, in which high Li+-transport dynamics titanate (TiO2) and capacity tin oxide (SnO2) were intimately integrated into hierarchical architecture nanocones, while unique spatial arrangement SnO2 component nano-cavities effectively accommodates change during lithiation/de-lithiation, hence rendering...
Sub-6 nm particles well-dispersed in carbon networks are prepared and the strategy sheds fresh light on design of ultra-fine particles.
SnO 2 –Zn 4 composite ceramics with a colossal dielectric permittivity and varistor behavior are prepared by traditional ceramic processing. By increasing bias voltage from 0 to 10 V at low frequency (~10 3 Hz) room temperature, the relative decreased rapidly about 20 000 several thousand, whereas radius of semicircle in complex impedance tail gradually disappeared. However, peak height position imaginary part modulus spectra were independent applied DC voltage. The slope deduced...
The challenges posed by poor conductivity and volume expansion during the lithiation–delithiation process have long been impediments to widespread adoption of molybdenum trioxide (MoO3) anode materials in lithium-ion batteries (LIBs). In this study, we prepare silver-decorated hydrogenated MoO3 (Ag/HxMoO3) particles through a facile reduction reaction further fabricate three-dimensional (3D) porous carbon supports via freeze drying thermal decomposition methods. resulting hybrid anodes...
A novel structure of anatase TiO2, nanocone-like TiO2 (TiO2-NC), is successfully prepared by a simple liquid-phase deposition method and used as an anode material. The morphology spatial arrangement the TiO2-NC greatly affects lithium storage, achieves sustained high storage performance (254.7 mA h g−1, corresponding to Li0.76TiO2) assembling into ordered spherical shells. structural analysis shows that exposed {001} facets nanosized help increase surface area well shorten diffusion path...
In this paper, mesoporous CuO with a novel architecture was synthesized through conventional hydrothermal approach followed by facile sintering procedure. HR-TEM analysis found that an interconnected pore structure has exposed high-energy crystal planes of (002) and (200). Theoretical calculations indicated the have superior adsorption capacity for H+ ions, which is critical excellent remarkable photocatalytic activity anionic dye. The to methyl orange (MO) at 0.4 g/L approximately 30% under...
